A new report shines a spotlight on problems facing ten of the nation's most endangered rivers, and possible solutions. It includes the Mississippi, which ranks sixth most at risk.

The river and its 30-million-acre floodplains, including in Missouri, are home to more than 850 fish and wildlife species. It's also a migratory corridor for birds, pollinators and some fish, and a crucial economic engine that supports 1.3 million jobs.

Tyler Schwartze, executive director of the Conservation Federation of Missouri, noted that despite the Mississippi's River's critical importance, it's in a state of decline because federal programs are under-resourced and not well coordinated.

"Missouri's watershed is entirely supported by the Mississippi River," he said. "So, it's important for all Missourians to engage and understand the importance of protecting our wildlife and all of our habitat across the river as well."

A bill before Congress, the Mississippi River Restoration and Resilience Initiative, would provide funds for projects in river states, cities and tribal nations to reduce runoff pollution, flood and storm risks and restore wildlife habitat. U.S. Rep. Cori Bush, D-Mo., is among the sponsors.

Schwartze stressed the importance of these types of projects. The report noted that the climate crisis and unsustainable development have exacerbated flood and storm risks, which carry more pollutants from the land into the river. He noted that the Mississippi provides drinking water to more than 18 million Americans, so it needs to be clean.

"Clean water is also vital for jobs, recreation and our entire way of life," he said. "It's vital to our nation's health; the fishing aspect of it is important. So many people rely on it - we just have to protect it for future generations to come."

The report mentioned that the legislation is based on another restoration initiative in the Great Lakes, which was successful and has seen bipartisan support. However, the Mississippi River bill has been sitting in a House subcommittee without action since last June.

June is National Rivers Month, and the Nevada Division of Environmental Protection (DEP) is getting ready to nominate Lake Tahoe and likely some of the state's mountain streams for special protection.

The state has been working for two years to come up with a list of Extraordinary Ecological, Aesthetic, or Recreational Waters, as required by the Clean Water Act.

Pam Harrington, field coordinator for Trout Unlimited, said the Silver State is playing a bit of catch-up.

"Nevada has lagged far behind in having special protections for the highest quality waters," Harrington observed. "Nearly every other state in the United States has a policy in place for this. So we've been behind."

Harrington said Tahoe would be a no-brainer, but she would like to see protections for some streams in the Ruby Mountains and for the Mahogany and Alder streams feeding into Summit Lake; important habitat for native Lahontan trout. The Nevada Conservation League is pressing the state to streamline the nomination process to make it easier for laypeople to participate.

Harrington added the changes would preserve the status quo and protect against future degradation.

"An ecological and aesthetic or recreational water in the state of Nevada would be afforded the highest level of protection," Harrington explained. "To disallow new pollution sources to be introduced into those waters."

The DEP has held multiple webinars with government, tribal, environmental and industry stakeholders. The state environmental commission gets the final say on the policy and is expected to take up the matter this fall.

Two decades of extreme drought have put a squeeze on Arizona's water supply, but a once-obscure state agency could soon be at the forefront of keeping the taps flowing.

The Arizona Water Bank, created in 1999, keeps track of any surplus water from the state's annual allotment from the Colorado River. But the river water has reached critical levels this year, triggering mandatory restrictions.

Virginia O'Connell, director of the Arizona Water Banking Authority, said the agency, for the first time, could be deciding how to get the "banked" water to where it's needed, while making sure the supplies last.

"So, this is a first for us," she said. "We'll be distributing credits for that purpose, or that entitlements have even been shorted. We're all working together to make sure that we're prepared, and we're ready to go when there is a shortage."

Arizona normally receives 2.8 million acre-feet of water per year from the Colorado River, but the restrictions will cut the state's allotment by 18%. O'Connell said the Water Bank currently manages about 3.75 million acre-feet of water credits.

She said most of the banked water is kept in storage by a group of utilities and other entities that have credits in the bank's watery "vault."

"Basically, it's an accounting system to keep track of how much water is stored, because that actually gives you ownership of that water," she said, "and then you can recover those credits in the future when you need that water."

In the 1990s, O'Connell said, state officials became concerned that unused portions of Arizona's water allotment could be claimed by other states. So, they set up the Water Bank to preserve any surplus for use during droughts and other shortages.

"Their task was to store all of the unused portion of Colorado River water in Arizona, and that water would be made available in the future when there are times of shortage," she said. "And that's kind of where we are now."

Under the current agreement, the U.S. Bureau of Reclamation will annually assess the available water supply. O'Connell said the Water Bank will use that data to determine how much water can be released and who will get it.

This Memorial Day Weekend, Maryland Department of Natural Resources responded to three fatal incidents; two drownings and a jet-ski collision. It is a reminder to anglers, boaters and swimmers to follow some basic safety tips to avoid tragedy.

Last year, Maryland had 145 reported boating accidents, six of which were fatal.

Lauren Moses, public information officer for the Maryland Natural Resources Police, said although the numbers of incidents are decreasing, some common mistakes keep cropping up. They include not keeping a proper lookout; someone on the boat to be aware of their surroundings.

Moses emphasized alcohol use is another issue.

"While it's not illegal to consume an alcoholic beverage while operating a vessel, it is illegal to be intoxicated, and that's because it impairs your judgment," Moses explained. "Intoxicated passengers can also easily fall overboard, and it can cause tons of issues."

Moses advised on waterways, as in other types of emergencies, people should call 911 as soon as possible. She added it is critical for everyone aboard a boat to wear a life jacket at all times.

The busy summer season will also bring plenty of swimmers to Maryland waterways. Moses stressed it is key for swimmers to stay alert about the weather and potential for sudden thunderstorms. She recommended following posted signage, particularly in state parks, and only swim in areas where a lifeguard is on duty.

"Because the waters' currents are very strong, and we tell people this all the time, regardless of how strong a swimmer you are, you may not be a match for those water currents," Moses pointed out. "It's very important to make sure that you do have your life jacket on, you're obeying what lifeguards are saying, and you are paying attention to the weather."

The next two Saturdays, June 4 and 11, are license-free fishing days in Maryland waters. You can download the U.S. Coast Guard app and the Maryland AccessDNR app for information on waterway conditions and warnings.
