Communities seeking relief from flooding caused by increasingly intense storms.

Fish seeking refuge from warming downstream waters.

Parents seeking solace when their child has been pulled into the undertow of the base of an artificial waterfall (aka a dam).

Landowners pouring money into failing, obsolete structures, or perhaps pretending they do not exist at all… just waiting for the next big storm to knock them down.

The reality of living in a world with a changing climate is real, and we must ensure that we actively work towards making our rivers and communities more resilient. Now is the time to revive our rivers and streams— the lifeblood of our nation. The good news is that we are making progress.

It has been another successful year of busting dams and reconnecting rivers and streams across America. Every year the dam removal movement continues to grow stronger. In 2018, 82 dams in total were removed from across the country. Communities in 18 states worked closely with various non-profit organizations, local municipalities, state and federal agencies to remove these dams and successfully reconnect more than 1,230 river miles.

Dams were removed in the following states: California, Connecticut, Georgia, Illinois, Indiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, and Wisconsin.

In 2018, California had the highest number of removals, surpassing Pennsylvania, the leading dam removal state for the past 15 years. The top three states removing outdated dams in 2018 were:

  • California – 35 dams removed
  • Pennsylvania – 7 dams removed
  • Michigan – 7 dams removed

Over the years, the number of dam removal projects have continued to increase, with most removals (1,355) occurring over the past 30 years. Pennsylvania has the highest number of removal projects so far (337 total recorded), while other states nationwide are also stepping up to the challenge (this year’s leader, California, has 148 total removals, followed closely by Michigan with 139). From 1912 through 2018, 1,578 dams have been removed in the U.S. to restore fish passage and access to habitat, eliminate safety hazards, and reduce future liability for owners and surrounding communities.

For over a century, the U.S. has led the world in dam building. However, like all infrastructure, dams don’t last forever. Twenty years ago this July, Edwards Dam was removed from the Kennebec River in Maine. It marked the first time the federal government ordered a dam removed because its costs outweighed its benefits; it garnered worldwide attention. The Kennebec is a resounding restoration success story, with millions of fish returning every year. It inspired a movement that continues to grow, nationally and globally.

Today, many local communities have come to understand that while in some situations dams can be beneficial, they can also cause a considerable amount of harm to river ecosystems. The American Society of Civil Engineers gives the nation’s dams a D grade in its report card on the nation’s infrastructure. Therefore, dams that were once the center of communities powering mills or supplying water for some industry are subsequently being removed after wearing down or no longer serving their intended purposes.

This year, American Rivers is applauding the great progress that environmental organizations, local municipalities, state and federal agencies, landowners, and others have made towards reestablishing natural river flow and functions through dam removal. However, we are ready to do more. There are hundreds of thousands, perhaps over a million, more dams out there. Many of them are coming to the end of their useful lives. American Rivers is committed to working with our partners across the country to find ways to increase the number of dams removed each year and empower communities to restore and reconnect their rivers. We cannot do it alone.

HIGHLIGHTS OF DAM REMOVAL AND RIVER RESTORATION EFFORTS IN 2018 INCLUDE:

Bloede Dam, Patapsco River, Maryland

The Bloede Dam was removed in 2018 as part of a larger plan— which included removal of the Union and Simkins dams in 2010— to restore more than 65 miles of spawning habitat for blueback herring, alewife, American shad, hickory shad, and more than 183 miles for American eel in the Patapsco River watershed. Originally built by a private company in the early 1900s to supply electricity to the cities of Catonsville in Baltimore County and Ellicott City in Howard County, the 34-foot high by 220-foot long dam, located in Patapsco Valley State Park, was most recently owned by the Maryland Department of Natural Resources. At the time of demolition, it no longer produced power or any other economic benefit, but contributed to numerous injuries and deaths, including at least nine dam-related drownings since the 1980s. Its removal reconnects habitat for one of the highest runs of river herring in the Chesapeake Bay.

Cleveland National Forest, California

The Cleveland National Forest removed 33 dams in total—18 dams from Holy Jim Creek, four in upper San Juan Creek, 10 in lower San Juan Creek and one from Trabuco Creek—in 2018. The dams were originally constructed for varying uses, including to create pools for a stocked rainbow trout fishery and provide water for fire suppression. However, years of disuse and, in some instances, a 40-year maintenance backlog resulted in the decision to remove these structures as a way to improve stream conditions and provide adequate fish passage and wildlife habitat. The efforts of the Cleveland National Forest demonstrate the power of coupling smart management of outdated water infrastructure with the potential re-establishment of extirpated species like the southern California steelhead trout.

Columbia Lake Dam, Paulins Kill, New Jersey

The 18-foot tall and 330-foot long Columbia Lake Dam was originally built in 1909 and, at the time of removal, owned by New Jersey Department of Environmental Protection Division of Fish and Wildlife. The project consisted of the removal of Columbia Lake Dam and a downstream remnant dam on Paulins Kill.  These two dams were physical barriers to fish migration and negatively impacted river flow. The removal of the Columbia Lake Dam restored access to more than 10 miles of historic habitat for migratory fish including American shad, restored 32 acres of floodplains, and provided safe and new recreational opportunities. The project is anticipated to increase abundance and diversity of macroinvertebrates, including freshwater mussels, that are indicative of good water quality.

  1. This is encouraging news! But I agree with Louise and Jennifer, we must turn up the pressure to REMOVE THE SNAKE RIVER DAMS, which are blocking salmon passage and starving orcas of their food supply! It’s IMPERATIVE that this be done AS SOON AS POSSIBLE. Please make this TOP PRIORITY.

  2. I’m adding my voice to urge the removal of the Snake River dams to save the orca whose virtually sole food is salmon and to increase the salmon population in general.

  3. Yes, the Snake River dams must be removed asap. The orcas are not going to survive and that is a terrible tragedy that can be avoided.
    I look forward to every dam being removed and higher water quality standards being made and enforced.

  4. Thank you for all you do to restore rivers around the country. I’ve been closely following the Bloede project, and have been impressed with how quickly the river has returned to it’s natural channel. I would love to see another Ambursen dam in my area removed. It’s the Warrior Ridge Hydro Dam on the Juniata River. I don’t think it generates enough electricity to justify it’s environmental impact. I’m not sure where to start, or if there’s even anything that I can do. It would be wonderful to see that section of river flowing freely. The reservoir is choked with sediment, and really stinks in the summer time.

  5. Thanks for all you’re doing to restore rivers around the country.

There’s another Ambursen dam in my area that I’d love to see removed. It’s the Warrior Ridge Hydro Dam on the Juniata River. I don’t think it generates enough electricity to justify it’s environmental impact. The reservoir is choked with sediment. I don’t know how to go about starting the process, though, or if there is even anything that I can do.

  6. this could be the answer to the orcas survival.
    please free the snake river dams to help them. they are starving because there are no chinook salmon to eat. the snake river dams are holding the salmon back. if the dams are not breached soon, these southern resident orcas face extinction. already there has been deaths from this special pod and many more are showing signs of going the same way. please don’t let it get that far, because once they are gone, then sadly they are gone forever. please do the right thing. these magnificent giants of the deep deserve the right to live. there are so many people backing this campaign on all different levels. from phoning and writing to gov inslee and co, to holding rallies to raise awareness. if the love alone could save these black and white beauties, then they would certainly live forever. sadly love does not nourish them. these aforementioned people supporting the dam breach are also part of the southern resident orca pod. this is because they are:

    Outgoing Resident Campaigners Against Starvation.

    these orcas means everything to us. please help them, before it’s too late.

    thank you

  7. Thank you for providing this thorough recap of 2018 dam removal activities across The U.S. Lots of great information, including the link to Learn More within the Things You Can Do section. Valuable learning aids, insights and tools.
