Opinion: California Drought Sharpens Perpetual Water Conflict

/in , , /by /CalMattersby Dan Walters

California never has enough water to meet all demands and even when supplies are relatively robust there’s a triangular competition over their allocation. Farmers, municipal users and environmental advocates vie for shares of water that has been captured by California’s extensive network of dams and reservoirs. Their battles are waged in the state Capitol, in Washington, in regulatory agencies and in the courts and over time, the trend has been a subtle shift of supplies from long-dominant agriculture to protecting flows for fish and other wildlife while maintaining the relatively small amount consumed in urban areas.

San Diego Launches $10-Million Assessment of Aging City Dams, Including Three Rated ‘Poor’

/in , , /by /Los Angeles Timesby David Garrick

San Diego is launching a $10-million effort to complete risk assessments of all nine of the city’s aging dams — only three of which are considered in satisfactory condition. City officials say the assessments are expected to reveal problems that will require an estimated $1 billion in repairs and upgrades in coming decades — and possibly some replacement dams in extreme cases. San Diego’s dams are among the oldest in the state and the nation. State officials said three dams are in “poor” condition — Hodges, El Capitan and Lower Otay — and three have been rated “fair”: Morena, Barrett and Lake Murray.

Governor Gavin Newsom on Monday issued an expanded “drought emergency proclamation” for 41 of the state’s 58 counties, citing above-average temperatures and dry conditions for April and May.

So far, Southern California has been spared the worst of the drought, and the San Diego County Water Authority has said it has supplies to withstand several dry years.

“Gov. Newsom’s latest drought emergency declaration is a grim reminder of the growing water supply challenges across California — and of the value of three decades of our collective dedication to use water efficiently combined with strategic investments that protect San Diego County from dry years,” said Gary Croucher, board chair of the water authority.

“Thanks to efforts of ratepayers, the water authority, and our 24 member agencies, we have sufficient water supplies for 2021 and the foreseeable future,” he said.

A recent UCLA study says that in the next 40 years, California could likely see a flood massive enough to cause nearly $1 trillion of damage, force millions of people to evacuate, and leave houses in California’s Central Valley 30 to 40 feet underwater. And the state is ill-prepared when it comes to infrastructure like dams that could prevent flooding.
