ST. LOUIS, Mo. - As Missourians have kept a watchful eye on extreme flooding in the state this spring, scientists at the National Oceanic and Atmospheric Administration are also watching. They are predicting the floods will contribute to a record-level "Dead Zone" in the Gulf of Mexico. The "Dead Zone" gets its name because there's not enough oxygen to support marine life, harming the health of one of the world's largest fisheries.

Kathleen Logan Smith, executive director of the Missouri Coalition for the Environment, says a more natural flooding pattern needs to be restored along the Mississippi and Missouri rivers.

"Where nature has the capacity to absorb more of that flood water and to treat more of the pollutants, some of our basic wetland restoration projects would really go a long way to keeping nitrogen and phosphorous out of the river in the first place."

Logan Smith says the dead zone is created by fertilizer run-off from farm fields. It is an annual event that peaks in July and fades in the fall as the waves and winds increase, she explains.

Logan Smith says many Missouri farmers use programs to minimize fertilizer run-off, but farmers need consistent incentives from the federal government.

"One of the biggest challenges that we have on the policy side is that Congress keeps cutting funding for these programs. Following through with our conservation commitment is constantly a question."

Missouri traditionally ranks high as one of the top states contributing pollutants to the "Dead Zone."

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.
