From the Fresno Bee:

With no room left right now in reservoirs, Valley farm water officials are actually relieved to see a break in the storms that pounded California in December and early January.

Dam tenders throughout the region have been releasing water to the Pacific Ocean so reservoirs will have room for unexpected spikes in storm runoff. It's done for public safety, but it means losing a lot of potential irrigation water.

The lull in storms would slow the releases and reduce losses. The drier weather also lets crews complete repairs on the Friant-Kern Canal, a key waterway for moving excess runoff to ground-water recharge basins.
