Big Battle Looms Over California Water Rights

/in , , /by /CalMattersby Dan Walters

California doesn’t have enough water to meet all demands even in wet years, and when drought strikes the competition becomes, to put it mildly, intense.

State and federal officials who must ration the restricted supply are beset with pleas from farmers, municipal water systems and advocates for the environment.

However, water managers must also contend with a bewildering array of water rights, some of which date to the 19th century, as well as long-standing contractual obligations and laws, both statutes and judicial decrees, on maintaining flows for spawning salmon and other wildlife.

Drought Hits South American River, Threatening Vast Ecosystem

/in , /by /AP Newsby Victor Caivano and Almudena Calatrava

The Paraná River, one of the main commercial waterways in South America, has reached its lowest level in nearly 80 years due to a prolonged drought in Brazil that scientists attribute to climate change.

At peril is a vast ecosystem that includes potable water for 40 million people, the livelihood of fishing communities and farmers, and the navigability of a major grain export hub.

The National Water Institute of Argentina has defined the low water level of the Paraná River, which goes through Brazil, Paraguay, and Argentina, as “the worst since 1944.”

General Manager Issues Statement Urging Region to Stay WaterSmart

/in , /by

Aug. 6, 2021 – San Diego County Water Authority General Manager Sandra L. Kerl today issued a statement in response to deteriorating water supplies across the West, highlighted by state officials taking the powerplant offline at Lake Oroville due to low reservoir levels and regulators restricting farmers’ access to Central Valley rivers.

“These developments are sobering reminders of the serious conditions facing residents, farms and businesses across the West. In support of regions where water supplies are severely strained, I urge San Diegans to do their part by voluntarily reducing use of our most precious natural resource by 15%, as called for by the governor.

“We have collectively done a great job developing new water supplies and reducing water use across the county – and we should remain vigilant in our efficient use of water. Some examples of actions people are taking to do their part include fixing leaks in irrigation systems and plumbing fixtures; irrigating in the morning or evening when temperatures and winds abate; washing only full loads of laundry and dishes; patronizing car washes that recycle water; using hoses with automatic shut-off valves; and using pool covers and garden mulch to reduce evaporation. Water-use efficiency information and incentives are at www.watersmartsd.org.

“By doing our part to stay WaterSmart, we will help California weather this extremely dry year and prepare for the uncertainties of the future.”

— Sandra L. Kerl, General Manager, San Diego County Water Authority

California Hydroelectric Plant Shut as Water Level Drops

/in , , /by /AP News

Drought-stricken California on Thursday shut down one of its largest hydroelectric plants because there’s not enough water to power it.

The six-turbine Edward Hyatt Power Plant was taken off-line after the water level in the Oroville Dam reservoir that feeds it sank to an historic low of less than 642 feet (195.7 meters) above mean sea level.

The reservoir in the Sierra Nevada foothills north of Sacramento was less than a quarter full.

Drought Will Force Western U.S. to Rethink Water Use, Experts Say

/in , /by /Newsweekby Troy Albert Schulz, Zenger News

A record hot summer has laid bare a stark new reality for many states on America’s West Coast: Amid rising temperatures and worsening droughts, many will need to systematically rethink the way they manage limited water supplies.

“One of the problems with rising temperatures is how it’s going to affect water management,” said Washington state’s official climatologist, Nicholas Bond. “Simply from an agricultural point of view, generally when it is warmer, the demands of crops for water goes up. At higher temperatures, crops need more to be able to thrive.”

Lake Mendocino Reaches Second-Lowest Level in History

/in , , /by /The Press Democrat (Santa Rosa)by Mary Callahan

Historic drought has reduced Lake Mendocino to its second-lowest level since it was built, leaving reservoir storage in startling condition with months of likely warm, dry weather still ahead.

The lake on Thursday held just more than 24,000 acre feet of water — a result of critically low rainfall totals that, combined, make 2019-21 the driest two years on record, the National Weather Service said.

Storage in the reservoir, completed in 1958 with a flood storage capacity of 122,400 acre feet, has dipped below 25,000 acre feet only three times before and below 24,000 acre feet only once — by half, according to Sonoma Water.
