The Natural Resources Conservation Service in Idaho has released the April Water Supply Outlook Report for the 2023 water year (WY23).  

Mother Nature did not get the memo that winter was supposed to come to an end. It was a very snowy March with records set at many SNOTEL stations and snow courses! The snowpack is near to well above normal across the entire state. Basins south of the Clearwater have the highest snowpack (SWE) percentages compared to northern Idaho.

Water supply conditions have turned around since last month with the very wet, cold March. All basins, apart from Upper Snake River water users, can expect sufficient water supply this irrigation season. This holds true especially if we have normal to above normal spring precipitation.

Current streamflow, snowpack, and precipitation data for Idaho can be accessed on the NRCS Idaho Snow Survey Webpage or on the interactive map.
