Too many fish deaths in the Sacramento- San Joaquin Delta are forcing the California Department of Water Resources to reduce the amount of water pumped to the Central Valley and southern California.
The number of protected Delta Smelt killed this year is nearing the annual limit set by the Endangered Species Act. Pumping stations have killed 232 smelt. Rules allow only 305 over the entire year.
Mark Corwin with the Department says the deaths illustrate the need for a new system, one that would include $14 billion twin tunnels.
