Blog: The Delta in April-June 2022 under TUCP
A lot has been said about the drought’s effect on water supplies for cities and farms, but little is said about how Delta fish are faring. Freshwater inflow to the Delta was about half of normal in April through June 2022 because of the State Water Board Order approving the Department of Water Resources (DWR) and the Bureau of Reclamation’s Temporary Urgency Change Petition (TUCP) for Delta operations. With some of this limited Delta inflow going to water users during April, May and June, little was going to the fish. The State Water Board granted the TUCP because Central Valley reservoir storage was so low at the end of winter in this third year of drought.
