People who live in the Southwest know it’s been especially hot and dry the past couple of years, but a new government report shows those conditions are actually historic.
Precipitation across multiple basins in six states from January 2020 through August 2021 was the lowest recorded since researchers started tracking with gauges in the late 1800s.
After water levels at a California dam fell to historic lows this summer, the main hydropower plant it feeds was shut down. At the Hoover Dam in Nevada — one of the country’s biggest hydropower generators — production is down by 25%. If extreme drought persists, federal officials say a dam in Arizona could stop producing electricity in coming years.
Severe drought across the West drained reservoirs this year, slashing hydropower production and further stressing the region’s power grids. And as extreme weather becomes more common with climate change, grid operators are adapting to swings in hydropower generation.
Experts in government, agriculture, water management and the environment stressed during a U.S. Senate hearing on Wednesday the danger that droughts fueled by climate change pose in the West, including the Colorado River Basin.
During a hearing before an Energy and Natural Resources Committee panel, witnesses said long-term solutions and an investment in water infrastructure are needed to combat the effects of climate change.
Climate change is poised to result in a worldwide water crisis, and international institutions and governments have not done enough to prepare, according to a report released Tuesday by the World Meteorological Organization (WMO).
The U.S. Army Corps of Engineers is known for damming rivers and building levees to keep waterways at bay. But a new initiative seeks natural flood control solutions as climate change brings increasingly frequent and severe weather events that test the limits of concrete and steel.
It only makes sense to use Mother Nature’s flood defenses as one of the tools to combat destruction from intense rains in the middle of the country and storms and sea level rise on the coasts, says Todd Bridges, who heads the Corps Engineering with Nature initiative.
Happy New Water Year. For those of us who work on California water challenges, the start of the new year isn’t Jan. 1; it’s Oct. 1, the official beginning of the state’s wet season. This is the time of year we start to look out over the Pacific for the storms we hope will bring life-giving precipitation, replenishing our rivers and streams, coating our mountains with snow, refilling our reservoirs and recharging our soils, forests, wetlands and groundwater.
Staying on top of your irrigation system – especially in the midst of a drought – can mean the difference between maximizing your water efficiency and unknowingly wasting water running down sidewalks unused into the storm drain. Follow these tips for a thorough checkup.
Turn on each valve of your irrigation system and observe how quickly water begins to run off your landscaping. Note the time when each runoff occurs. For some systems, this could be immediate. For others, it may take as long as five minutes.
Make sure spray irrigation is never running for longer than eight minutes at any one time.
Take notes on your irrigation plan, and turn off your irrigation until you can fix the following issues:

Several things can be done to minimize runoff due to irrigation. This is among the most important factors in using irrigation efficiently.

As Tracy Schohr goes about her day, water is always on her mind. She’s thinking of it as she rides an all-terrain vehicle around the pasture, looks up hay prices and weather forecasts, and collects data on grazing and invasive weeds for a scientific study. Schohr is a rancher and farmer in Gridley, California, where her family has raised beef cattle and grown rice for six generations. She also aids in scientific research to study drought and other agricultural issues with the University of California Cooperative Extension.
Two years ago, a pact to safeguard the West’s shrinking water supplies took effect at a ceremony high above the Colorado River.
On a terrace overlooking Hoover Dam, water officials from seven states that rely on the river had gathered to sign a deal in hopes of preventing reservoirs from falling to critically low levels.
Federal officials project more bad news for the drought-stressed Colorado River, which provides water to Las Vegas and much of the Southwest.
The Bureau of Reclamation issued a report last week saying there is a high likelihood over the next few years that California, the river’s largest water user, will join Nevada, Arizona, and Mexico in seeing cuts to its allocation.
