California’s only native sunfish, the Sacramento perch, survived catastrophic floods in the 1860s and was so abundant that it was a regular staple in San Francisco’s markets before invasive species decimated its population.
The Bureau of Reclamation on August 15, released the Colorado River Basin August 2023 24-Month Study, which determines the tiers for the coordinated operation of Lake Powell and Lake Mead for 2024. These operating conditions, which are based on existing agreements under the 2007 guidelines and lower basin Drought Contingency Plans, will be in effect until the near-term guidelines from the Supplemental Environmental Impact Statement (SEIS) are finalized. Reclamation is currently analyzing the consensus-based Lower Division States proposed alternative for the SEIS.
Based on projections in the 24-Month Study, Lake Powell will operate in a Mid-Elevation Release Tier with a 7.48 million acre-feet release in water year 2024. Consistent with existing agreements, Lake Mead will operate in a Level 1 Shortage Condition – an improvement from the Level 2 Shortage Condition announced last year – with required shortages by Arizona and Nevada, coupled with Lower Basin Drought Contingency Plan water savings contributions. Mexico’s water delivery will be reduced consistent with Minute 323.
A research effort tracking water scarcity around the world shows California, Arizona and other Western states are experiencing water stress at high levels similar to arid countries such as Saudi Arabia and Qatar.
The analysis by researchers with the World Resources Institute found that all seven states that rely on the Colorado River face high or extremely high water stress. Arizona ranked first for the most severe water stress in the country, followed by New Mexico and Colorado, while California ranked fifth.
California will likely not face any cuts in Colorado River supply in 2024, according to a new forecast released on Tuesday by the U.S. Bureau of Reclamation. The agency said heavy snowpack and rains last winter mean planned reductions can be eased slightly from more urgent levels last year.
In 2021, our team at UC Merced found that covering California’s extensive network of irrigation canals with solar panels could make significant contributions to both clean energy and water conservation, serving two of the state’s most pressing needs at once.
California officials agreed today to extend operations at three natural gas plants on the Southern California coast in an effort to shore up California’s straining power grid and avoid rolling blackouts.
The controversial and unanimous vote that keeps the plants open came from the State Water Resources Control Board, which oversees the phaseout of natural gas facilities that suck in seawater and kill marine life.
Federal officials said Tuesday they will ease water cuts for Western states reliant on the Colorado River in 2024, thanks to a slightly improved outlook, but long-term challenges remain.
The river serves seven U.S. states, Native American tribes and two states in Mexico. It also supports a multibillion-dollar farm industry in the West and generates hydropower used across the region. Years of overuse by farms and cities, and the effects of drought worsened by climate change has meant much less water flows today through the Colorado River than in previous decades.
The U.S. government announces water availability for the coming year months in advance so that cities, farmers and others can plan. The first mandatory cuts that magnified the crisis on the river went into effect in 2022, followed by even deeper cuts this year due to drought, poor precipitation and less runoff from the headwaters in the Rocky Mountains.
Conservation measures and a wetter winter have improved the river’s health, leading to cuts being dialed back, starting in January. It won’t lead to dramatic changes because those affected have been living with water cuts for two years — or are voluntarily conserving water.
Federal officials this week are expected to ease water cuts for 2024 under a slightly improved outlook for the Colorado River’s health, though long-term challenges remain. The river provides water for seven U.S. states, 29 Native American tribes and two states in Mexico. It also supports a multibillion-dollar farm industry in the West and generates hydropower used across the region. Years of overuse by farms and cities and the effects of drought worsened by climate change has meant much less water flows today through the Colorado River than in previous decades.
A sizzling month marked by record heat waves, major wildfires, melting sea ice and a burgeoning El Niño will go down in the books as the hottest July on record — at least until next year, federal officials said. The planet and its oceans roasted last month as global average temperatures soared 2.02 degrees above average, making July 2023 not only the hottest July ever, but very likely Earth’s warmest month in at least 174 years of record keeping.
A landmark court decision that Montana is violating its youngest residents’ rights to a clean and healthful climate could have legal repercussions well beyond the Treasure State. Judge Kathy Seeley of the 1st Judicial District Court in Montana found Monday that youth in the state have a “fundamental constitutional right to a clean and healthful environment, which includes climate” as she struck down two laws that bar state agencies from considering the climate effects of fossil fuel projects.
