OPINION: Colorado River Drought Contingency Plan Is Necessary Now

Last week, the seven Colorado River basin states — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — sent a letter to Congress calling for federal legislation to authorize the Drought Contingency Plan (DCP). Congressional House and Senate committees are holding hearings on the plan. It’s a historic moment for a river that supports two countries, seven states, 40 million people, 5.5 million acres of agricultural land, 22 federally recognized tribes, 11 national parks, seven wildlife refuges, four national recreation areas, and seven endangered species.

Atmospheric Rivers: California Could Experience More Intense Rains In The Future

Imagine a river flowing through the sky – and all of its water dropping down to earth. That’s kind of what happens during many winter storms on the west coast. A so-called “atmospheric river” is a long, flowing band of water vapor – typically a few hundred miles wide – that contains vast amounts of moisture. When it moves inland over mountains, the moisture rises, causing it to cool and fall to earth as rain or snow. Duane Waliser of NASA’s Jet Propulsion Laboratory says atmospheric rivers are often beneficial, because they provide about half of California’s fresh water supply. But strong atmospheric river systems can also be dangerous – especially when they stall, or produce rain on top of snow.

Spillway Could Be Used Next Week, DWR Says

The newly-renovated Oroville Dam spillway could be used as early as next week, the state Department of Water Resources said Tuesday. DWR is “closely monitoring Oroville reservoir levels and current forecasts,” the water agency said in a press release. With storms forecast in the Feather River basin, DWR said it is taking steps to prepare for use of the main spillway by the first week of April. Although the state water agency said the spillway was usable in October 2017 if needed, water has not flowed in significant amounts since the spillway crisis in February 2017, when a hole in the enormous concrete structure led to use of the emergency spillway concrete weir for the first time in history and eventually the evacuation of more than 188,000 downstream residents.

Twelve Bay Area Water Agencies Award Outstanding Student Projects In Water Disciplines

Eleven Bay area water, wastewater and recycled water agencies have joined forces to form the Excellence in Water, Wastewater and Recycled Water Research award category at the annual Contra Costa County Science & Engineering Fair. The water division recognizes outstanding student projects in the disciplines of water.  The category is one of many as part of fair which was held at on March 14-16 at Los Medanos College in Pittsburgh, CA.
