Groups Call on Trump Administration to Curb Wasteful Use of Colorado River Water

Environmental groups are demanding that the Trump administration exercise the federal government’s authority to curb wasteful water use in an effort to address the Colorado River’s chronic water shortages. In a petition submitted Tuesday, the Natural Resources Defense Council and nine other groups called for the U.S. Bureau of Reclamation to enforce a provision of federal regulations stating that water deliveries in California, Arizona and Nevada “will not exceed those reasonably required for beneficial use.”

How California Farmers Can Recharge the Drained Aquifers

In parts of California’s Central Valley, so much groundwater has been pumped out of the ground to deal with the region’s persistent drought that the land is starting to sink in. Underground aquifers — layers of sand, gravel, clay, and water — are vital resources that communities can turn to when surface water is scarce. But when more water is pumped out of aquifers than is put back in — as is happening in the southern part of the valley — it can cause the ground to slowly contract, like a drying sponge.

Map Shows Fluoride Bans on Drinking Water in US States

Florida has become the latest state to restrict fluoride additives in public drinking water, after Governor Ron DeSantis signed the bill into law this week, and a Newsweek map shows how similar legislation is progressing in the rest of the U.S. The legislation, part of the broader Florida Farm Bill, prohibits local governments from adding fluoride or other medical additives to municipal water systems.

Colorado River Needs ‘Shared Pain’ to Break Deadlock Over Water Use, Experts Say

The Colorado River makes up about half of San Diego County’s imported water supply. Now, California and the six other states that use the Colorado River are deadlocked about how to share it in the future. The current rules for dividing its shrinking supplies expire in 2026.

Jacobs Awarded Contract to Operate Largest Water Recycling System in Southern California

Jacobs has been selected by the West Basin Municipal Water District to provide operations and maintenance (O&M) services for the Edward C. Little Water Recycling Facility and four associated sites. The five-year contract covers what is described as the largest water recycling system of its kind in the United States.

Water Deliveries to Mexico Resume

The United States resumed water deliveries to Mexico after initially denying the request for the emergency transfer from the Colorado River, according to Agriculture Secretary Brooke Rollins. Under a 1944 treaty, Mexico is expected to deliver 1.75 million acre-feet of water to South Texas every five years. This five-year period ends in October, and so far, Mexico has delivered 530,730 acre-feet.

California Reservoirs Exceed Normal Water Levels

The latest California water data showed the state’s largest reservoirs are nearly 20% higher than normal. The San Pablo Reservoir in the East Bay is nearly full, currently at 75% capacity, and will likely reach capacity as it collects more water from the melting Sierra snowpack. The reservoir is one of four East Bay MUD-managed water supplies.

House Republicans Vote to Remove California Fish From Endangered Species List

House Republicans passed a measure Thursday that would repeal the government’s decision to place California’s longfin smelt, a finger-sized fish, on the endangered species list. House members passed the resolution, introduced by California Rep. Doug LaMalfa (R-Richvale), in a 216-195 vote that followed party lines. The resolution now goes to the Republican-controlled Senate.

 

Cotton, Gallego Introduce Bipartisan Bill to Strengthen America’s Water Infrastructure Against Cyber Attacks

Senator Tom Cotton (R-Arkansas) and Senator Ruben Gallego (D-Arizona) today introduced the Water Cybersecurity Enhancement Act, bipartisan legislation to help public water systems protect against and respond to cyberattacks, which have become increasingly frequent in recent years.

Rapid Snowmelt Threatens US West Water Supply Outlook

Rapid melts across the U.S. West have caused snowpack to disappear up to four weeks early in some areas — wreaking potential havoc on the region’s water supply, federal meteorologists warned Thursday. These conditions have particularly affected parts of Utah, Colorado and New Mexico, causing some basins to shift from above-average snowpack to “snow drought,” according to an update from the National Integrated Drought Information System (NIDIS).
