March storms increased snowpack in the northern half of the West but didn’t provide much relief for the dry southern half, according to data from the U.S. Department of Agriculture’s National Water and Climate Center (NWCC) in its April 2014 water supply forecast.

According to the Natural Resources Conservation Service (NRCS), most of Idaho, Montana, Wyoming, and northern parts of Colorado and Utah are expected to have near normal or above normal water supplies, according to the forecast. Far below normal streamflow is expected for southern Oregon, California, Arizona, New Mexico, southern Utah and western Nevada.
