  • Agencies race to fix plans to sustain groundwater levels
    by Nick Cahill on May 1, 2024 at 3:09 pm

    Seeking to prevent the California State Water Resources Control Board from stepping in to regulate groundwater in critically overdrafted subbasins, local agencies are working to correct deficiencies in their plans to protect groundwater. With groundwater sustainability agencies formed and groundwater sustainability plans evaluated, the state water board has moved to implement the 2014 Sustainable Groundwater Management Act, or SGMA. … Under probation, groundwater extractors in the Tulare Lake subbasin face annual fees of $300 per well and $20 per acre-foot pumped, plus a late reporting fee of 25%.

  • As Great Salt Lake nears key level, Utah finds inspiration elsewhere to help lake’s recovery

  • Problems with Glen Canyon Dam could jeopardize water flowing to Western states
    by Alastair Bland on May 1, 2024 at 1:52 pm

    A new memo from the U.S. Bureau of Reclamation is raising concern about the infrastructure at the Glen Canyon Dam and its ability to deliver water downstream should levels at Lake Powell continue to decline. Environmental groups are calling it “the most urgent water problem” for the Colorado River and the 40 million people who rely on it. … Without upgrades to the dam’s infrastructure, the bureau’s ability to get water downstream to the lower Colorado River basin as required by the Colorado River Compact could be in jeopardy. Even after record-breaking snowfall in 2023 and an above average 2024 winter, Lake Powell remains at about 32% full, according to data from the bureau. And scientists estimate flows in the river have decreased by roughly 20% over the last century, with warming temperatures resulting in a 10% decrease in runoff.

  • Sweeping Colorado River settlement will bring water, equity to Navajo communities
    by Alastair Bland on May 1, 2024 at 1:46 pm

What’s clear is that the settlement, known as the Northeastern Arizona Indian Water Rights Settlement Agreement, is about equity, human rights and securing access to water for the next 100 years for the Navajo people. … The agreement would settle all of the Navajo Nation’s water rights claims in Arizona, which includes the Colorado River Upper Basin, the Colorado River Lower Basin, Little Colorado River Basin and some groundwater. The proposal will be put into legislation and voted on by the Navajo Nation Council before it is sent to Congress, where lawmakers could make their own adjustments.

  • Opinion – Statewide water supply target supports California’s manufacturers
    by Alastair Bland on May 1, 2024 at 1:33 pm

    Water use in California is typically thought of in three parts: water for the environment (50%), water for agriculture (40%), and water for communities (10%) per the Public Policy Institute of California (PPIC). As a result, “ag” is the sector of the economy that comes to mind first when we talk about the state’s water supply. But the rest of California’s economy also requires water. California’s manufacturers – one of the state’s largest industry sectors, accounting for 11.8% of state GDP – need water.  -Written by Lance Hastings, President and CEO of the California Manufacturers & Technology Association.​ View Original Article read more
