Reservoirs and rivers are overflowing as storms have pounded California this winter, and after years of drought that should be good news. The problem is that misguided environmentalism is wasting the water windfall and failing to store it for a non-rainy day.
Hydrologic records indicate that this year could be the wettest on record in California. Statewide snowpack measures 160% of average. Precipitation in Palm Springs exceeds the historic norm by more than 50%. Lo, the desert is actually blooming. Most of the major reservoirs in the north are full, and some are releasing hundreds of billions of gallons of water to prevent flooding and make room for the melting snowpack this spring.
While farmers and communities downstream can capture some of the discharges, millions of acre-feet will invariably flow into the ocean due to lack of storage capacity and rules to protect endangered fish species. One problem is that while the state population has increased 70% since 1979, storage hasn’t expanded. Water districts in southern California have developed small local reservoirs and groundwater basins, but what’s most needed is storage in the north where most of the rain and snow falls.
The Public Policy Institute of California estimates that five proposed reservoirs could add four million acre-feet of storage capacity at a cost of $9 billion. Yet environmentalists have opposed every significant surface storage project for three decades. The state is even razing four hydroelectric dams on the Klamath River that green groups complain impede fish migration.
Ah, the fish. Regulations intended to protect smelt and salmon have limited pumping at the Sacramento-San Joaquin River Delta. As a result, some seven million acre-feet of water that was once available for Central Valley farmers and Southern California is flushed into San Francisco Bay each year.
Meanwhile, a 60-mile dry riverbed on the San Joaquin River that hasn’t borne fish since the 1940s is being restored at a cost of $1.7 billion to farmers and state and federal taxpayers. The river restoration is expected to divert an additional 170,000 acre-feet each year, but it could be more since the Chinook salmon that environmentalists want to revive require cool temperatures—meaning more water—to spawn and survive. Government biologists are spending millions of dollars to truck (literally) salmon around the valley while trying to calibrate optimal temperatures and water flows. Yes, these salmon have chauffeurs.
