Meager Snowpack Adds to Colorado River’s Woes, Straining Flows to Southern California

Many of California’s reservoirs have filled nearly to capacity this year with runoff from the ample snowpack in the Sierra Nevada. But the situation is very different along the Colorado River, another vital water source for Southern California, where a very dry spring has shrunk the amount of runoff streaming into reservoirs. The latest forecast from the federal Colorado Basin River Forecast Center shows that the river’s flows into Lake Powell will probably be about 46% of average over the next three months.
