Snowpack Levels By State

Recently the Natural Resources Conservation Service Snow Survey came out with their by state April 1st report Water Supply Level Outlook Report. Here is a quick overview of the reports state by state.
In Idaho arm, dry conditions dominated the March weather scene, and greatly increased the probability of water shortages or marginally adequate water supplies for the coming summer. As of April 1, about half of Idaho’s basins were reporting less than 50% of median snowpacks.
Due to an unusually warm winter, Oregon continues to experience record low snowpack levels. Record low April 1 snowpack levels were measured at 76% of Oregon’s snow monitoring sites, and only 52 out of 147 sites across the state recorded any snow at all. Summer streamflow is expected to be well below normal and water shortages are likely throughout the state.
Seventy-four percent of Washington state’s long-term monitoring sites have set new record low snowpack. The April 1 statewide SNOTEL readings were 22 percent of normal shattering the previous record low of thirty-three set in 2005. The only area that has a bit of good news is the Methow River Basin, which is reporting 79 percent of normal while almost everywhere else is at 50 percent or less of normal readings.
Currently in Colorado snowpack is 69 percent of normal, down from 87 percent last month according to SNOTEL and snow course observation sites. This ranks Colorado mountain snowpack third from the minimum year in 2002 out of a 30 year period of record. The persistent bright spot in the state is in the South Platte River basin where snowpack was 110 percent of normal last month.
