MORGANTOWN, W.Va. -- June has been National Rivers Month, and in West Virginia, conservation groups are celebrating the results of decades-long efforts to clean up acid mine drainage from the Cheat River.

Fish can once again be found in the Cheat Canyon, and both Sovern Run and Big Sandy Creek are almost ready to be removed from the state's list of impaired streams.

Stephen Toth, general partner at Blue Gold Development, which has helped with the cleanup project, said the Cheat River is recovering, but treatment should be ongoing to ensure the contamination doesn't return.

"It's something that you basically have to do every 10 to 20 years," Toth explained. "Even though we did a project this year, in about 10 to 15 or 20 years, that's probably going to have to happen again. So, funding is of major importance for this."

In the past two decades, Cheat River restoration efforts have received more than $5 million in support, and research showed between 2000 and 2013, the restoration work reduced acid mine drainage-related pollution in the Cheat watershed by more than one million pounds, according to the Environmental Protection Agency.

Toth added the river cleanup has also boosted local tourism and brought more dollars to small businesses.

"It means so much to the community that lives here, and also tourism, and brings people from out of state," Toth observed. "It's just remarkable what they've done, and I'm very thankful to be a part of this."

Laura Delaney, who owns a brewery in Bruceton Mills, agreed. She said she's watched economic development and quality of life improve with river restoration work.

"I mean, this is a rural farming community," Delaney remarked. "We depend, you know, in so many ways, on having a clean water supply."

Groups like Friends of the Cheat said they next plan to focus on removing the Albright Power Dam on the Cheat River, arguing reconnecting the Cheat will have positive ecological and economic benefits.

DURANGO, Colo. - Colorado's rivers and streams supply drinking water and outdoor recreation opportunities, and support biodiversity and wildlife, but less than 4% are fully protected.

New research by Conservation Science Partners found the majority of the state's 15,000 unprotected river miles could qualify for Outstanding National Resource Waters designations. The group's lead scientist, Caitlin Littlefield, said Colorado waterways are under increasing threat due to climate change and population growth.

"We really need to get out ahead of these changes and protect these rivers and streams that have the most integrity as soon as we possibly can," she said. "It's not something we're going to regret, and will only serve our wildlife, and our ecosystems and our human needs, in the future."

The report, commissioned by The Pew Charitable Trusts, found the waterways meeting the most criteria for protections were in the western half of the state. It said Colorado's highest-value rivers - those that haven't been modified and contribute significant value to people, wildlife and ecosystems - include the headwaters of the Dolores River, Roubideau Creek and Taylor River.

Ashleigh Tucker, managing partner at 4Corners Riversports in Durango, said people travel great distances to experience Colorado's rivers and streams for paddle-boarding, rafting and fishing. She added that their value has become even more pronounced in the pandemic, when closures found more Coloradans seeking activities outdoors.

"Colorado's economy relies on outdoor recreation," she said, "and so it's definitely something that we need to be supporting and protecting for future generations, so that people can continue to come and see our beautiful rivers, and see them clean and free-flowing."

Outdoor recreation contributes $12.2 billion to the state's economy, according to the Outdoor Industry Association. Scientists identified a total of 662 river miles that scored in the top 25% statewide for meeting all Outstanding National Resource Waters criteria. Some 133 river miles ranked in the top 10% are headwater streams in the Gunnison, San Isabel and San Juan national forests.

ST. PAUL, Minn. - Minnesota continues to battle aquatic invasive species in certain lakes. As the state fights these threats, there are calls for the Department of Natural Resources to develop a more robust management plan.

The state's overall blueprint for combating zebra mussels and other habitat-disrupting pests was written in 2009. DNR leaders have said they're putting a new plan together, with invasive species detected in more waterways this summer.

Jeff Forester, executive director of Minnesota Lakes and Rivers Advocates, said he hopes it's a comprehensive strategy, with better coordination of on-the-ground efforts.

"Nobody really knows what anybody else is doing, and it's not targeted toward specific and achievable goals. It's not coordinated," Forester said of the current plan.

He said the DNR should guide detailed collaboration between lake associations, county governments and others doing prevention work. The DNR has anticipated a new plan over the next year, and said it will include such information as the impact of climate change.

A bill in this year's Legislature called for a new management plan every five years. Ann Pierce, the DNR's deputy director of ecological and water resources, said that kind of timeline would require more federal reviews, potentially delaying prevention funding from Congress.

"Having to have the federal government have to review it, which takes time - sometimes up to a year - it's going to put kind of a roadblock in some of that annual granting process," she said.

However, Minnesota Lakes and Rivers has contended that those issues shouldn't be connected. It noted that the federal grants are a narrow scope in combating aquatic invasive species, and thinks the state should focus on its own plan. The bill's sponsor said there's room for compromise, but will keep pressing for urgency.

Carroll Schaal, lakes and rivers section chief for the Wisconsin DNR, which last updated its management plan in 2019, acknowledged that it was a big undertaking, and federal involvement was only one part of the approach.

"[The] federal money at stake isn't that significant," he said. "I mean, we're very appreciative of it. But you know, we're able to, with our own resources, adjust to the current conditions."

On the Minnesota side, the DNR said its planning doesn't prevent making an alteration if a crisis prompts one. But it insists required updates aren't optimal in carrying out a broader plan.

ALBUQUERQUE, N.M. -- Opponents of rollbacks to the Trump-era Clean Water Act say 90% of New Mexico's waters were left unprotected and hope a recent court decision will be a turning point.

A federal judge ruled the Trump administration's 2020 "Navigable Waters Protection Rule" was too flawed to keep in place. That means for now, instead of falling under federal jurisdiction, the status of ephemeral or intermittent streams will be subject to case-by-case determinations.

Rachel Conn, deputy director of the water advocacy group Amigos Bravos in Taos, said arid states such as New Mexico need their own rules.

"We are a very dry state, as we all know, and we have many waters that don't flow year-round, and it is all of those waters that had been left unprotected," Conn observed.

The rule removed protections for hundreds of thousands of intermittent streams and wetlands that feed and support the Rio Grande. It also left others across the country vulnerable to pollution from development. Prior to the ruling, the Biden administration said it planned to repeal the Trump rule and issue new regulations under the Clean Water Act.

Conn argued a new approach is critical to New Mexico because it's the only Western state the Environmental Protection Agency has not authorized to manage its own discharge permitting program to protect surface water.

"We're one of only three states that hasn't gotten that delegation to do the permitting for discharges into waters," Conn explained. "You have to go through that process with the EPA to get that delegation."

Conn added water-advocacy groups want the Biden administration and agencies it oversees to implement flexible rules to address arid conditions.

"A one-size-fits-all approach that has been implemented in the past often results in western states like New Mexico being forced into a regulatory paradigm that's really been developed for more temperate conditions," Conn contended.

Farmers and real-estate developers opposed the 2015 change to clean-water laws under the Obama administration as federal overreach, while President Donald Trump called it unconstitutional.
