NIDIS and its partners launched this snow drought effort in 2018 to provide data, maps, and tools for monitoring snow drought and its impacts as well as communicating the status of snow drought across the United States, including Alaska. The Klamath Basin is currently in extreme (D3) and exceptional drought (D4), according to the U.S. Drought Monitor, and the low snowpack heading into spring will likely intensify the drought conditions given that some reservoirs are near historic lows. there were unusually high amounts of snow SNOTEL sites are remote backcountry weather stations that measure snow and transmit the data wirelessly, which help inform.
