Ever had an aquarium? You probably had no more than a handful of fish to care for. Imagine if you were raising millions and millions of fish, including a variety of species with different needs. Let's throw some freshwater mussels in there, too.

You're starting to look like a national fish hatchery, where biologists blend layers upon layers of science and technique to successfully raise and release fish and mussels that will support our waters and fishing pastime and industry.

Best of 2012 5) Conserving the Chesapeake Bay

We're bringing in the new year with a look back at our milestones for 2012. Check back each day for featured events and activities from across the Northeast!

Why is it so important that we safeguard the nation’s largest estuary and its tributaries? The Chesapeake Bay Watershed supports more than 2,700 plant and animal species. In addition to all the plants and animals that rely on the Chesapeake Bay, more than 15 million people reside or work within the watershed. In 2012, the Service continued to conserve this important resource and its environment.

Best of 2012: 1) Protecting and restoring our waters

We're bringing in the new year with a look back at our milestones for 2012. Check back each day for featured events and activities from across the Northeast!

Our rivers and streams connect us to just about everything we do, from drinking and energy to fishing and other recreation. Some of the water barriers that we’ve put in place to harness this precious resource, including road-stream pipes (culverts), dams and dikes, have seriously impacted wildlife and water quality. Of the estimated six million barriers across the U.S., many are now also obsolete and hazards to human health and safety.

Pa. mussels help restore streams in Ill., Ohio and WV

We love freshwater mussels so much that we extended our month-long series to tell you about work to restore and protect freshwater mussels and their homes in Pennsylvania. Today you're hearing from Lora Zimmerman, the assistant supervisor of Contaminants and Conservation Planning Assistance in our Pennsylvania office. This series highlights the importance of freshwater mussels to the Northeast landscape and the concerted efforts underway to ensure their future in our waters.

Pennsylvania is known for a lot of things—spectacular trout fishing, abundant energy resources, intensely rivaled hockey teams—but one of the lesser known treasures of Pennsylvania is its native freshwater mussels.  

Species almost lost elsewhere are known from the Allegheny River and French Creek in western Pennsylvania, and they are the envy of several neighboring states where the mussels have either been lost or populations are too small to survive without assistance. For example, although it remains in only five percent of its historical range, the northern riffleshell continues to have thriving populations in Pennsylvania. Likewise, the clubshell mussel also has stronghold populations in the Commonwealth.

Clubs, riffles and rays of New York

This post is part of a series running all month on freshwater mussels, highlighting their importance to the Northeast landscape and the concerted efforts underway to ensure their future in our waters.

 The Allegheny River basin holds globally significant populations of four species of mussels federally listed as endangered.  They are northern riffleshell (Epioblasma torulosa rangiana), clubshell (Pleurobema clava), rayed bean (Villosa fabalis) and snuffbox (Epioblasma triquetra).  

Surveys in the upper Allegheny River basin in New York and Pennsylvania have found populations of these species in the past, but portions of the mainstem Allegheny River and its tributaries remain un-surveyed or have incomplete surveys -- an obstacle to truly achieving recovery.

Today you're hearing from Cheryl Daigle, the community liaison and outreach coordinator for the Penobscot River Restoration Trust. This post is part of a series running all month on freshwater mussels, highlighting their importance to the Northeast landscape and the concerted efforts underway to ensure their future in our waters.

Working on a river restoration project that is focused on restoring 11 species of sea-run fish -- including the enigmatic shortnose sturgeon and leaping wonder of salmon -- offers many fascinating moments of discovery about rivers, community, and restoration of place.

Yet, I never imagined freshwater mussels would invite the depths of thought I had while helping to relocate exposed mussels to deeper habitat during the removal of the Great Works Dam and subsequent lowering of the impoundment to a natural river flow.

Giving mussels a boost in Tenn.'s Powell River

Today you're hearing from Jess Jones, a restoration biologist with the Service's Virginia Field Office, on releasing the largest group of three endangered mussels in the Powell River. This post is part of a series running all month on freshwater mussels, highlighting their importance to the Northeast landscape and the concerted efforts underway to ensure their future in our waters.

Every once in a while everything just works out. 

Today was such a day -- cool and sunny, an early fall afternoon on the Powell River in northeastern Tennessee, where biologists and students worked together to release endangered mussels. Heavy rains occurred the week before, but the water level dropped just in time to stock them in the river, 5,500 oyster mussels (Epioblasma capsaeformis), 1,000 Cumberlandian combshells (Epioblasma brevidens), and 27 snuffbox (Epioblasma triquetra). The young mussels were 1-2 years old and about 20-30 mm long.

Reviving a river: Free-flowing waters at Great Works Dam

Each week, our folks at the Maine field office are driving by to check on the progress of the Great Works Dam removal, part of the Penobscot River Restoration Project.

The majority of the heavy lifting at Great Works is complete, so we'd like to share a series of photos capturing the incredible progress made since June this year -- a representation of many years of conservation efforts.

Freshwater mussel conservation in western New York

This post is part of a series running all month on freshwater mussels, highlighting their importance to the Northeast landscape and the concerted efforts underway to ensure their future in our waters.

Nestled between Lake Ontario and Lake Erie in western New York, the Service's Lower Great Lakes Fish and Wildlife Conservation Office is located in an incredibly unique area. Part of the reason this area is so interesting is the high number of streams with freshwater mussels.

Freshwater mussel populations are in decline all over the country. Pollution and habitat loss are two of the leading causes of the population decline. As the human population grows and cities spread out, more roads are built, many of which cross streams. When those road crossings are installed correctly, they cause no problems.

However, due to budget constraints and lack of training for the installers, many crossings are under-sized or incorrectly installed. This causes a major problem for fish and other critters that live in the stream. The road crossing becomes a barrier to fish migration, as well as the migration of other species, including freshwater mussels.

Reviving a river: Checking in at Great Works Dam

Each week, our folks at the Maine field office are driving by to check on the progress of the Great Works Dam removal, part of the Penobscot River Restoration Project.

Our Maine hydro licensing coordinator, Steve Shepard, says, "Imagine running these rapids. I hear it was done last week, though the fish have been doing it for weeks!"

A growing appreciation for freshwater mussels


Brett Hillman Today you’re hearing from Brett Hillman, a biological science technician for the Service’s New England Field Office, as he recounts his work with freshwater mussels at the Service's Missisquoi National Wildlife Refuge in Vermont. Brett assists the endangered species biologists and has the great pleasure of working with a wide variety of wildlife. This post is part of a series running all month on freshwater mussels, highlighting their importance to the Northeast landscape and the concerted efforts underway to ensure their future in our waters.

Before I began my job in the New England Field Office, I will admit that I didn’t have a great appreciation for mussels.

I knew that they were an important component of aquatic ecosystems, but I didn’t understand quite how important. And while I’ve spent countless hours searching for and identifying species of many other taxa, from birds to bugs to plants, mussels never captured my interest. Now that I’m fully immersed in mussel ecology, however, I am definitely gaining some more respect for these underrated invertebrates.

Freshwater mussels are one of the most imperiled taxa in the country. According to Patty Morrison, a mussel expert and biologist at the Ohio River Islands National Wildlife Refuge, 76 out of the approximately 300 native mussel species in the U.S. are federally listed, six of which have been listed within just the past two years.

Not just rocks: The mussels of our rivers and streams


Today you’re hearing from Meagan Racey, who handles public affairs and media relations for Ecological Services, on her recent encounter with freshwater mussels. This post is part of a series running all month on freshwater mussels, highlighting their importance to the Northeast landscape and the concerted efforts underway to ensure their future in our waters.

The sky beamed blue above, and the sun shined down on me below as I sliced the clear water with my paddle—shwoosh down the right side of the kayak, and shwoosh down the left side. From the shoreline, a great blue heron watched me wearily, and up ahead a bald eagle peered from the treetop. Minnows darted under the water and water bugs glided across the top.


It’s hard to beat a day on the water. My trip down a portion of New England’s longest river, the Connecticut River, started at Greenfield, Mass., and amid all the beautiful details I mentioned above, one unmentioned characteristic struck me the most – the littering of freshwater mussels poking up from the bottom of the clear river.

Reviving a river: Checking in at Great Works Dam

Each week, our folks at the Maine field office are driving by to check on the progress of the Great Works Dam removal, part of the Penobscot River Restoration Project.

As the Penobscot River Restoration Trust says: "The next best thing to the sight of a newly restored, free-flowing stretch of river? The sound of water coursing through natural ledges and cobbles. An amazing transformation has been taking place on this stretch of the Penobscot River!"


Reviving a river: From the Atlantic Salmon Federation

Andy Goode, vice president of U.S. programs
for the Atlantic Salmon Federation.
Today you're hearing from Andy Goode, the vice president of U.S. programs for the Atlantic Salmon Federation, an international conservation organization dedicated to the conservation, protection and restoration of wild Atlantic salmon and the ecosystems on which their well being and survival depend. ASF is a partner in the internationally recognized Penobscot River Restoration Project, re-opening nearly 1,000 mile of habitat for endangered Atlantic salmon, sturgeon, river herring and eight other species of sea-run fish in Maine.


The Penobscot Project offers a rare, far ranging, and for the foreseeable future, our only opportunity to restore a significant run of Atlantic salmon in the southern range of the species. For the first time in 200 years this project will directly address the primary threat to Atlantic salmon restoration by reducing multiple dams in Maine’s largest salmon river, thus offering the real potential to reverse the longterm decline of salmon in the United States.

Roanoke makes river more popular for fish and recreation

Two years later, and the new and improved bridge that crosses the Roanoke River in Roanoke, Va., is still a gift to the fish that make the river their home, as well as to the people of the city.

Completed on May 20, 2010, the installation of the new bridge was the final step in the Wiley Drive Bridge replacement project that including replacing the previous bridge with one that would better serve the fish and other visitors to the Roanoke River.

The main purpose of the project was to allow more movement for groups of Roanoke logperch, a fish protected under the Endangered Species Act, that have been documented in upper and lower sections of the river. The former bridge acted almost as a dam, keeping the populations separated from one another and lowering genetic diversity.

Reviving a river: Checking in at Great Works Dam

Each week, our folks at the Maine field office are driving by to check on the progress of the Great Works Dam removal, part of the Penobscot River Restoration Project.

Our Maine hydro licensing coordinator, Steve Shepard, tells us, "The folks with the big toys are making steady progress!"

Work is starting on the remains of the Legacy Dam which dates back to days of hydromechanical power when there were reportedly 120 mills between Old Town and Bangor.

Reviving a river: Checking in at Great Works Dam

Each week, our folks at the Maine field office are driving by to check on the progress of the Great Works Dam removal, part of the Penobscot River Restoration Project. 

The two big timber crib sections in the background are nearly demolished! Two excavators in the foreground are demolishing another concrete section with hoe rams (impressive hydraulic hammers that have 4-5 tons of impact).

In the center of the photo, the excavator near the dam is completing a fish passage channel that will become the thalweg of the river, or its lowest point. After that is complete, the coffer dam will be removed, and the water will drop to something close to the new level.

Reviving a river: Checking in at Great Works Dam

Each week, our folks at the Maine field office are driving by to check on the progress of the Great Works Dam removal, part of the Penobscot River Restoration Project. 

Demolition is proceeding smoothly with the help of very low flows and the ability to work within the coffer dam. The outer timber crib section is nearly gone and the next one may be chewed up by the end of the week.
