The Bureau of Reclamation announced that the forecasted inflow to Shasta Lake is currently projected to be greater than 3.2 million acre-feet and declared we are in a “Shasta Non-Critical” year.
The California Department of Water Resources published an updated Bulletin 120 last week that shows a large increase in Shasta Lake inflow since the May 1 forecast. The forecasted inflow to Shasta Lake is now greater than 3.2 million acre-feet, changing the previous determination of a “Shasta Critical” to “Shasta Non-Critical” water year as defined in certain Central Valley Project contracts.
A Shasta critical year is declared when the forecasted inflow to Shasta Lake, (the cornerstone reservoir in the federal Central Valley Project), is at or below 3.2 million acre-feet. Storage in the reservoir as of mid-April was just over 3.7 million acre-feet.
The Central Valley Project serves farms, homes and industry in the Central Valley, San Joaquin Valley and the San Francisco Bay Area. The project provides water for 6 of the top 10 agricultural counties in California.
