Atlantic Sturgeon: A Perfect Poster Fish for the Blueprint

The following first appeared in the fall 2016 issue of Save the Bay magazine.

"They need our help," explains Doug Myers, CBF Senior Scientist and in-house sturgeon expert. "Sturgeon have had a lot happen to their habitat over the years. Today, the Chesapeake's only confirmed breeding population is in Virginia's James River. We need to expand their reach so if something disastrous were to happen on the James, the fish wouldn't be wiped out."

A lot has happened, too, since we featured sturgeon in the Summer 2011 issue of Save the Bay magazine. The year after our article ran, the National Oceanic and Atmospheric Administration Fisheries listed Atlantic sturgeon as endangered.

In our story, "Last Refuge of the Dinosaur Fish," Matt Balazik—at the time a Virginia Commonwealth University graduate student and sturgeon census taker—was pictured tossing a 70-pound sturgeon back into the James River. Today Matt, now Dr. Balazik, an integrative life sciences Ph.D., is a faculty researcher at VCU's Rice Rivers Center. The next step for the fish, he says, is habitat designation. "We've learned a lot in the James. As of a couple months ago," Balazik says, "we've identified two spawning groups in the James." According to Dr. Balazik, each group has different staging and spawning grounds. One group spawns in the spring, the other in fall. "I think it's massive to protect the spawning grounds that we are zeroing in on using telemetry data." Although protecting the area "where the magic happens," is important, he says, "the whole river plays an important role in the health of the fish, from the headwaters to the mouth of the Bay where they spend their first years of life."

On the case at CBF is Doug Myers. While the endangered species listing goes a long way toward protecting the fish, Myers says NOAA also needs to designate critical habitat for sturgeon. Under the Endangered Species Act, critical habitat is defined as "the geographical area occupied by the species at the time it is listed on which are found . . . features essential to the conservation of the species." It can also include areas not currently occupied by the species but that are imperative to its restoration. In the Chesapeake Bay, 453 miles of river are proposed for critical habitat and include feeding and spawning grounds.

Rivers with areas under consideration for critical habitat include the Susquehanna, the Potomac, the Rappahannock, the York, and the James. But the question arises: How are sturgeon to get to these rivers, especially the Potomac and Susquehanna, for the fall spawning season when the main body of the Chesapeake Bay suffers from annual low-oxygen dead zones in the summer?

Myers argues there is a direct link between the fish and the goals of the Chesapeake Clean Water Blueprint"Once the critical habitat is designated, we'll have the Endangered Species Act . . . adding emphasis to the Blueprint."

"Because of their oxygen requirements, Atlantic sturgeon are the perfect poster fish for the Blueprint," says Myers. The Blueprint is a federal-state plan designed to improve water quality across the watershed by reducing pollution from agriculture, runoff, air, and wastewater. In February, the U.S. Supreme Court decided not to hear the American Farm Bureau Federation's appeal attempting to throw out the Blueprint. The court's decision let stand two lower courts' rulings that the Blueprint stands on firm legal ground. Moreover, as a federal and state program, the Blueprint and its regulatory and funding provisions have a "federal nexus" to the sturgeon listing. So we expect that the critical habitat designation will force a more intimate coordination between federal agencies. 

Atlantic sturgeon require rough, gravely bottoms for spawning and clean, oxygenated waters. Polluted runoff, which carries toxins, bacteria, garbage, and sediment, flushes into our waterways after a rainstorm. This debris and sediment make its way to river bottom and threaten spawning grounds. By reducing the amount of pollution-laden sediment reaching these rivers, water quality improves for all species that reside and come to spawn. 

As bottom feeders, Atlantic sturgeon are dependent on benthic organisms like mussels, worms, and small crustaceans. And sturgeon depend on a minimum of 6 mg/L of oxygen in the water to survive. A NOAA Fisheries' critical habitat designation, however extensive and inclusive it ends up, is vital to sturgeon survival and will be another tool to combat the ills the Chesapeake Bay faces. 

Atlantic sturgeon doesn't reach maturity until age 10 to 15 and only spawns every two to three years, making recovery slow. Sturgeon are anadromous fish that enter the Chesapeake Bay in the spring and fall to spawn in the upper reaches of its rivers. At least that's what they use to do. In the late 19th and early 20th centuries, driven by a demand for their eggs, otherwise known as caviar, Atlantic sturgeon were nearly depleted. The fish faced additional obstacles like dams blocking their way up river and reduced spawning grounds. Boat and ship strikes also threatened the large fish. The issues sturgeon have faced have brought the species near extinction.

Readers who want to witness a sturgeon, can contact Captain Mike Ostrander (mike[at sign]discoverthejames.com) and sign up for one of his sturgeon tours. The two-and-a-half hour, Thursday-night excursions are scheduled to leave Hopewell, Virginia, at 5 p.m. on September 1, 8, 15, and 22. Captain Mike has been a river guide on the James for 16 years. He "found it natural to want to share the opportunity to see a breaching sturgeon. When you see one," he says "it's like the end of a fireworks show."

This dinosaur-era fish has endured millennia. In spite of overharvesting and habitat destruction, we may be witnessing a comeback, but we need to protect and restore the historic spawning and feeding grounds and the sturgeon's pathways to and from those grounds so this species has a fighting chance.

—Jen Wallace, CBF's Managing Editor

UPDATE: On August 31, CBF submitted its official comments to the NOAA Fisheries office, urging them to make water quality a top priority as they designate critical habitat for the Atlantic sturgeon and manage it into the future. More than 8,000 advocates joined with us in standing up for this ancient and important fish—the Chesapeake's largest and oldest. Click here to see our letter and the signatures of those supporters. We expect to hear a final decision on the Atlantic sturgeon habitat designation by June 3, 2017. Stay tuned for updates!

 


This Week in the Watershed

George Washington once wrote in his diary that he "went a dragging for Sturgeon," fishing for a culinary staple in the 18th century. But it's more than being mentioned in George Washington's diary that makes the Atlantic sturgeon an American legend. The sturgeon, the Bay's largest native fish, was here long before the days of the American Revolution. Dating back 120 million years, the Atlantic sturgeon once thrived in the waters in and around the Chesapeake Bay. But these dinosaurs of the Chesapeake are now threatened with extinction after their populations plummeted from poor water quality, habitat destruction, and overfishing.

All is not lost, however. The National Oceanic and Atmospheric Administration (NOAA) Fisheries is now proposing to designate "critical habitat" for this important fish. Designating areas as "critical habitat" can make a world of difference for the sturgeon. But water quality must be a priority in designating this habitat. If it isn't, sturgeon populations could remain under threat as poor water quality creates barriers between important sturgeon habitat and interrupts the species' life cycle.

Sign our petition by September 1st to tell NOAA Fisheries to make water quality a top priority as it designates sturgeon critical habitat and manages it in the future.

What's even better—the sturgeon won't be the only beneficiary from improving water quality. By implementing the Chesapeake Clean Water Blueprint, we all will experience the benefits of clean water, from expanded recreational opportunities, to improved public health, to massive economic benefits. Our children deserve to see a Bay full of clean water with a thriving population of this historic fish. Sign our petition now!

Good News about Oysters

Oyster-planting-1200
3.2 million spat on shell were planted in the South River this July. Photo by Erika Nortemann.

Persuading microscopic oyster larvae to "set" on old shells is as simple as placing plenty of both into a large round tank of circulating Bay water and leaving them together for several days. Right?

Not hardly. This Chesapeake miracle is absolutely dependent on good water quality. Some years, successive sets die off, handcuffing restoration programs.

But not this year, at least so far. CBF's MD Oyster Restoration Center at Shady Side has been able to produce a record number of spat (i.e. baby oysters) on shell, the universal currency of restoration. "The spring and summer have been extremely kind to us," said Capt. Karl Willey as he deftly maneuvered Patricia Campbell, CBF's 60' oyster planter, around Thunder & Lightning, an oyster reef in the South River that is open to harvest by watermen wielding hand tongs. "The hatchery at the University of Maryland Horn Point Laboratory started producing larvae early—in April—and has continued. We've seen strong spat sets in our tanks since then. We've actually gotten ahead of schedule, with 31 million spat set on shell and placed on restoration reefs in the Little Choptank...Now we have July to work small projects with some of our partners. That's why you found Kate [South River Federation Executive Director Kate Fritz] and me counting spat on the dock this morning." 

Indeed, as Dan Johannes, Pat Beall, and intern Patrick McCabe loaded spat on shell into the large bins on either side of Patricia Campbell's long foredeck, Karl and Kate carefully examined a random sample of several dozen shells, counting the pinhead-sized spat on each. Eight-to-twenty spat on each shell allowed him and Kate to estimate how many spat the big boat would be planting on this day: 3.2 million. 

Loading and counting completed, the crew and several volunteers, including Kate's Board Chair, Kevin Green, climbed aboard for the one-hour run up to South River. We slowed briefly to watch a large pod of dolphins fishing in the river's mouth, then got down to work on a sanctuary reef 11-14' deep off Larrimore Point. As Kate and Kevin watched on the foredeck, Dan started up the hydraulic system that tilts the bins full of spat on shell inward to the conveyor belt that runs down the center of the foredeck. Pat and Patrick began to regulate the flow of 1.4 million spat on their shells into a steady stream on the belt, all moving forward to drop onto a rotating "planter wheel" at the bow that throws them out in a circle 10-12' in diameter. Meanwhile, a GPS antenna mounted beside the wheel sent a continuous signal of our track to the electronic display in front of Karl at the helm, recording the data on a memory card. This technology arms Karl with the data to know everywhere this program has planted since 2003.

We dropped another 0.5 million spat on shell on an 8' sanctuary reef tended by John Flood, an South River Federation Board member emeritus, and 0.3 million on another sanctuary off the mouth of Little Aberdeen Creek. Finally, we moved to Thunder & Lightning, to drop the last 1 million in 10-12' where local watermen partners would be able to harvest them once they grow out in two-to-three years.

Tiny predators like mud crabs that live on the reefs eat spat, but survival from spawn to adult for these guys set in concentration in our tanks is higher than natural sets in the wild," Karl said. "The density at which we plant [5 million spat on shell per acre] produces dense clusters." 

At the end of the month, Patricia Campbell and her crew will partner with the Coastal Conservation Association/Maryland to set 72 concrete reef balls with spat and place them onto the MD DNR's Tilghman Island Artificial Reef, in 18-20' of water due west of the island. The reef balls themselves have a special story: they have all been built by high school students in masonry classes, expressly for this purpose.

After three decades of bad news about oysters, imagine being able to get ahead of schedule with good news. Here's hoping we can make it last...

The Chesapeake's Oldest and Largest

Atl-sturgeon_iStock

There's an ancient fish in our Chesapeake Bay, and it's threatened with extinction on our watch.

That's right: A local fish—the Atlantic sturgeon—survived Ice Ages, just to become endangered millions of years later by poor water quality, destruction of its habitat, and overfishing.

National Oceanic and Atmospheric Administration (NOAA) Fisheries is proposing to designate "critical habitat" for Atlantic sturgeon. CBF will be weighing in on this critical designation—and we hope you will, too.

The Atlantic sturgeon has a long history in the Chesapeake Bay, earning the title of its oldest and largest fish species. These prehistoric fish have been around for 120 million years, and each one can live 60 years, grow to 14 feet in length, and weigh up to 800 pounds.

But their numbers have dwindled, and, in 2012, the Atlantic sturgeon was added to the Endangered Species List. Now, NOAA Fisheries must identify those areas that are most important for the survival of the species—the "critical habitat" needed for spawning, rearing, feeding, and migration to other important habitat.

The link between the health of sturgeon and the health of the Bay and its major rivers is an important one. The Bay's degraded water quality has created barriers between important habitats, interrupting the species' life cycle. By restoring water quality through the Chesapeake Clean Water Blueprint, we will be helping to recover one of the region's oldest, most extraordinary fish species.

From Virginia's James, Pamunkey, and Mattaponi Rivers to Maryland's Potomac River to Pennsylvania's Lower Susquehanna to the Delmarva Peninsula's Marshyhope Creek and Nanticoke River, sturgeon have spawned and survived across the Chesapeake Bay region. They'll need these areas—along with the healthy water quality that will allow them to get to these areas safely—in order to survive.

What can you do to help? Public comment on the critical habitat designation will be taken until September 1. Stay tuned for updates on how you can weigh in to support our recommendations for designation. In the meantime, more information on the proposal and comments can be found here.

Wow. Modern-day dinosaurs right here in the Chesapeake Bay. Don't your kids and grandkids deserve that same sense of wonder?

Let's work together to ensure that a fish that has been here for millions of years will still be here, spawning and someday thriving, for generations to come. 

—Bill Goldsborough, CBF's Director of Fisheries


The Good, the Bad, and the Ugly of Summertime Fishing

Locklear Story 0416 II Sam Loustanua"How will I know when a fish bites?" "Young Sam" asked his grandfather, Sam Locklear. Both Sams and younger brother, Nate, were fishing the Severn River with me last summer. It's always a treat to have enthusiastic ten- and seven-year-old anglers aboard, especially when a trip starts like this one. The words were hardly out in the air before two chunky white perch climbed onto the teasers on Young Sam's line, nearly taking the rod out of his hands. 

We were fishing a 12-14-foot-deep restoration oyster reef near the U.S. Naval Academy. This particular reef, an underwater point jutting out into the channel, is an example of where oysters thrive. The reef is elevated in the water column where currents bring the oysters food, carry away waste, and attract other critters—like worms, barnacles, grass shrimp, and mud crabs—that in turn attract predators like white perch and rockfish. We could see the perch on my skiff's fishfinder. The Severn has more successful restoration reefs like this one—they form the happy side of this story. 

The other side isn't as pretty. With supper on ice, the Sams, Nate, and I went upriver to a 25-foot-deep reef that showed hard bottom but no fish. It's a survey site for an upcoming restoration project, so we got out an electronic temperature/salinity/oxygen meter and lowered its sensor's ten-meter cable to get a profile of the water column. As usual for summer here—and in too many other parts of the Chesapeake system—the dissolved oxygen measured below two milligrams per liter from the bottom up to about 15 feet. That's a lethal level for perch and rockfish and stressful even for crabs. In fact, on the bottom that day, the level was below 0.5 mg/l—low enough to kill worms. No wonder the fishfinder screen was blank below 15 feet. That's what a "dead zone" looks like. This is the ugly side of the story. It illustrates why we concentrate oyster restoration in shallower water. 

As Memorial Day approaches, we've got dead zones on our minds. But why do dead zones form each summer? From human-caused nitrogen pollution. Take a look at this excellent graphic from YSI, Inc. (the maker of my oxygen meter). It concentrates on the Gulf of Mexico, but the global map shows hypoxia ("the environmental phenomenon where the concentration of dissolved oxygen in the water column decreases to a level that can no longer support living aquatic organisms") all over the Earth, including the Chesapeake.

What can we do about it? We have a plan called the Chesapeake Clean Water Blueprint, and it's slowly turning the bad stuff around while we celebrate successes like these new oyster reefs. Want to make sure that Young Sam, Nate, and thousands of other youngsters have a healthy Bay to grow up around? Click here to find out how you can help.

What's Bill Seeing in the Field: Opportunistic Eagles

For more than 30 years, CBF Educator and photographer Bill Portlock has been exploring, documenting, and teaching the wonders of the Chesapeake and its rivers and streams. With his vast, intimate knowledge and experience with the watershed, we thought who better to check in with about what he's seeing in the field right now . . .

Bill
On a recent spring morning, I was fortunate to be in my skiff on Cat Point Creek, a tidal tributary of the Rappahannock River in Richmond County, Virginia.

Eagle-rich Fones Cliffs, just four miles upstream from Cat Point Creek, is a unique Bald Eagle concentration zone, with thousands of eagles from Labrador to Florida as well as native Virginia birds using the area for nocturnal roosts, foraging, and (for residents) nesting. Many eagles spill over into Cat Point to forage on its abundant fish, primarily blue catfish and gizzard shad, but at this time of year there are migratory river herring and shad in the river. That the herring spring run to spawn is tied to bald eagle reproduction is yet another interwoven cycle of nature. It is a cornucopia of protein for a couple of months.

Bill1One eagle caught my attention that day by successfully capturing an alewife, a river herring just in from the ocean to spawn, in an oxbow of the creek. After the successful catch, he flew to a low branch over the water to eat his catch. Males are about 20 percent smaller than females, and when females are incubating eggs, males do most of the fishing. I allowed the ebbing tide to quietly drift me toward the scene. Today, this eagle was more focused on consuming his meal than paying attention to me.

Alewives and blueback herring are related to hickory and american shad and are members of the herring family (Clupeidae). These are anadromous fish, meaning they spend the majority of their adult lives at sea and migrate up coastal rivers in the spring to spawn in freshwater.

Bald eagles reproduce earlier than most birds in the Bay region, starting nest construction or repair in December and January. Egg laying and incubation takes place as early as December (and can run until March) in the Chesapeake Bay region. The hatching and rearing of young eagles takes place from March to June. Thus, the spawning run of herring and shad feed young eagles and the parents.

There were dozens of Wilson's snipe feeding on insect larvae, worms, and other invertebrates in the arrow arum marshes. These medium-sized shorebirds frequent the creek during winter before migrating north in April. Two pairs of blue-winged teal and a handsome pair of common mergansers were the only ducks present. But the main show on Cat Point that morning was this adult Bald Eagle capturing and eating this 12-inch river herring right in front of me.

4At one time in the not-too-distant past, coastal rivers supported thriving herring and shad industries, with millions of fish harvested each year. However, populations of these fishes declined dramatically in the last century due to dam obstructions, overharvesting, and pollution. The river herring fishery (which includes the alewife and the blueback herring) has been one of the most valuable in the Bay, with annual catches once exceeding 8 million pounds in Maryland and 30 million pounds in Virginia.

Opportunistic feeders, bald eagles also catch ducks, turtles, and small mammals (muskrat size). But fish make up the bulk of their diet, especially in warmer months. Availability of non-migratory gizzard shad and the introduced blue catfish make up the majority of prey captured now.

But on this day, a migratory alewife was the prey of this hungry eagle. Drifting slowly in my skiff to within 30 feet of the perched eagle, I was able to quietly watch and photograph the eagle. I  felt privileged to be there.

This Week in the Watershed

Blue-crab-1200
Lovers of blue crab raised their hands (or claws) in triumph this week, after receiving the good news that a survey found Maryland's blue crab population has increased 35 percent. Photo by Brian Brown.

If the fight to save the Bay were a baseball season, there would be both victories and losses, with swings of momentum in every direction. These swings were witnessed in Maryland's General Assembly, presenting both successes and disappointments for clean water advocates over the 90-day session. Bad news first: the Poultry Litter Management Act (PLMA), a measure to hold large poultry integrators responsible for excess poultry manure, didn't get beyond committee hearings this year. Silver lining: the hearings for the PLMA started the conversation, and our fight to reduce phosphorus pollution in the Bay and Eastern Shore waterways is far from over.

Time for some good news: the Sustainable Oyster Harvest Act passed, which will provide critical pieces of scientific data still needed to help inform management of Maryland's public oyster fishery. Other good news: the Greenhouse Gas Reduction Act has been signed into law, making Maryland one of the nation's leaders in greenhouse gas reduction; a budget passed favorable to many environmental agencies and programs that play key roles in Chesapeake Bay restoration, and several bad bills that would have endangered water quality were defeated. Learn more about the 2016 Maryland General Assembly.

In addition to the Annapolis happenings, there was more good and bad news from the watershed this week. Again, bad news first: we have known for some time the Susquehanna River is sick. The environmental group American Rivers agrees, declaring this week that the Susquehanna is the third most endangered river in the United States. A critical step to help the Susquehanna is officially listing it as an impaired waterway. An official impairment status will designate the river for additional study and new levels of investment in restoration. Stand with CBF and its partners in urging Governor Wolf and Pennsylvania’s Department of Environmental Protection to list the Lower Susquehanna River as impaired.

The good news: a survey by Maryland's Department of Natural Resources found that the blue crab population has grown 35 percent. While science tells us the current crab population is still below recommended levels, the increase in population is a positive sign of improving water quality by implementing the Chesapeake Clean Water Blueprint.

As all baseball fans know, the season is quite long, and no team ever has, or ever will, go undefeated. But we will continue to fight for the Bay, and work to ensure along the way there are plenty more victories than defeats.

Oyster reef-1200

Oysters just might be the most important critter in the Chesapeake Bay. A keystone species, not only do they help clean the water (an adult oyster can filter 50 gallons of water every day!), oyster reefs also provide critical habitat for other fisheries. Despite the unique and critical role oysters play in water quality, they are the only major public fishery in the Bay that isn’t managed using scientific information. 

To add science to oyster management, several Maryland legislators have introduced a bill called the Sustainable Oyster Harvest Act of 2016. The bill would put the public oyster fishery on the path towards more sustainable, science-based management by requiring a new study to determine the current oyster population and recommend appropriate scientific indicators for management.

Currently, scientists can only roughly estimate how many oysters are in the Bay. Compared with other fisheries, our lack of knowledge of the oyster population is startling. To ensure there is a sustainable oyster fishery in the Bay for generations to come, we need to incorporate sound science in our policy decision making. Take action by telling your legislator right now that you think science should play a role in how Maryland manages its oyster harvest.

Susquehanna River: By the Numbers

Susquehanna By the Numbers-1200

The Susquehanna River is unquestionably the most important river in the Chesapeake Bay watershed. To grasp the Susquehanna's sheer size and significance, take a glance at the numbers in the infographic above. Not only is this vital waterway a critical economic resource and a bastion of cultural heritage in Pennsylvania, it also has a tremendous impact on the health of the Chesapeake Bay, with the Susquehanna providing half of the Bay's freshwater flows.

In light of the importance of the Susquehanna, the current health of the river is concerning. Agricultural runoff, acid mine drainage, and polluted urban runoff are threatening this powerful economic engine. A glaring example of this is the health of the smallmouth bass found in its waters. One of the most prized freshwater sport-fish species, the Susquehanna's smallmouth bass fishery once attracted anglers from all over the world. Pollution has taken a toll however, as various diseases have wreaked havoc on the smallmouth bass, with bass being found with lesions, sores, and abnormal sexual development in which males grow eggs in their testes. When smallmouth bass are diseased, weakened, or otherwise stressed, we know things aren’t right.

It's long past time for the Lower Susquehanna to be listed as impaired. This listing would designate the Susquehanna for additional study and new levels of investment in restoration. Stand with CBF and its partners in urging Governor Wolf and Pennsylvania’s Department of Environmental Protection to save this vital waterway by listing the Lower Susquehanna River as impaired.

Water Quality Plays Key Role in Return, Survival of Bald Eagles

The following first appeared in the York Dispatch.

A new season of the Commonwealth's most popular, high-flying reality show is back online.

Millions are expected to log on to the Pennsylvania Game Commission (PGC) website and watch as live-streaming cameras show the drama of nature at several bald eagle nests in the Keystone State. The experiences open windows onto nature like never before.

People went online more than one and a-half million times last year to see a pair of bald eagles raise two eaglets in a nest near Codorus State Park. They saw the entire process, from "nestorations" in January, laying of the eggs in February, hatching in March, and the eaglets leaving the nest in June, as it happened. This is the tenth year for the nest and the second that cameras and microphones are there.

Another popular nest is in a Hackberry tree in the town of Hays, along the Monongahela River, near Pittsburgh. The camera and sound are sponsored by the Western PA Audubon Society. This is the third season a camera has watched the nest that eagles first used in 2013. Sadly, neither of the two eggs in the Hays nest were viable last year. But the year before, three eaglets thrived and successfully left the nest.

Those who lognon to the live cameras realize quickly that waterways play a key role in the lives of bald eagles and nesting sites are never far from water. Streams, lakes, and rivers are key habitat for bald eagles. In the winter, they congregate in tall trees near open water, to spot prey and shelter at night.

Fish make up almost 90 percent of a bald eagle's diet. Is there a more majestic sight than an eagle soaring and scanning open water, swooping gracefully downward, and then with their talons, plucking prey through the water's surface?

The Codorus eagles feed fish from Lake Marburg, Codorus Creek, and other York County waterways to their young ones. Bass from the Monongahela is often on the menu at the Hays nest.

So it's no secret that the survival and recovery of bald eagles in Pennsylvania are dependent on clean water, and the availability of healthy fish and other aquatic life. It is yet another reason we must make progress in restoring the 19,000 miles of waterways in Pennsylvania that are polluted. About 350 miles of waterways in York County are impaired.

The runoff of nitrogen, phosphorus, and sediment is damaging our rivers and streams, and the Commonwealth is significantly behind in meeting its commitment to reduce polluted runoff.

Also, consider findings of the latest multi-year study of the causes behind the deaths of young smallmouth bass, and lesions and spots on older smallmouths in the Susquehanna River. Some of those fish are served up in bald eagle nests throughout central Pennsylvania.

Endocrine-disrupting compounds and herbicides, and pathogens and parasites, are the two most-likely causes of diseased and dying fish in the Susquehanna. They are part of a perfect storm of compounds such as cosmetics, detergents, pharmaceuticals, and hormones in animal and human waste, that find their way into the diets of bald eagles and other wildlife.

On the bright side, the resurgence of bald eagles nationally and in Pennsylvania is an endangered species success story.

Habitat destruction, contaminated food sources, and illegal shooting took bald eagles to the brink of extinction. The road to recovery took major turns when the pesticide DDT was banned in 1972, and in 1978 when bald eagles were listed as endangered under the Endangered Species Act.

In 1980, there were only three known pairs of bald eagles nesting in Pennsylvania. Re-introduction began in the 1980's when the Game Commission brought 88 eaglets to the Commonwealth from Canada, raised them on specially constructed towers, and released them into the wild. Bald eagles were removed from the federal List of Endangered and Threatened Wildlife in the lower 48 states in 2007.

By 2008 the number of nesting pairs in Pennsylvania had grown to 150. In 2013 there were nests in all but a handful of Keystone State counties and more than 270 nesting pairs.

Clean water counts in Pennsylvania. It is a legacy worth leaving future generations of humans and bald eagles.
