This week in… the State Board

Last week, the State Water Resources Control Board issued the first mandatory water restrictions in the state’s history. The rules, which take effect June 1st, will be in place until February 2016. Under the new restrictions, every water service provider with more than 3,000 connections must conserve a specific percentage of their 2014 per capita use. Percentages range from 8 to 36 percent. Any utility not meeting its target faces fines up to $10,000 per day.

On May 1st, the State Board issued curtailment orders to junior water rights holders in the Sacramento River watershed, adding to the curtailment orders that have already been issued for junior water rights holders in the San Joaquin River, Scott River, Antelope Creek, and Deer Creek watersheds. This Monday, the State Water Resources Control Board announced it would soon be issuing curtailment orders to users with the most senior water rights.

In other news…

  • San Jose Water Company will begin imposing mandatory water rationing next month, making San Jose the largest California city to impose rationing.
  • The state has started building an emergency salinity barrier in the Sacramento-San Joaquin Bay Delta. The barrier is intended to prevent saltwater intrusion and protect the quality of water pumped from the Delta for irrigation and urban use.
  • The U.S. Forest Service estimates the drought has killed at least 12 million trees in California’s national forests, which are already at an elevated risk from wildfires.
