The Natural Resources Conservation Service (NRCS) in Idaho has released the final Water Supply Outlook Report for the 2021 water year.

This spring has been one of the driest on record, and the NRCS snow-monitoring network shows that snow remains only at the highest elevation sites across our state.

“Water supply across the state varies depending on local drought intensity, duration, and reservoir carryover storage from last year,” said Erin Whorton, Hydrologist-Water Supply Specialist for NRCS Snow Survey in Idaho. “Without additional late spring or early summer precipitation, unregulated rivers will be at minimum or near record low flow levels by mid-to-late summer. We anticipate the combination of dry weather conditions, and the early and strong onset of irrigation demand, will cause reservoirs to reach minimal levels and have minimal carryover into water year 2022.”

Streamflow, snowpack, and precipitation data for each basin can be accessed on the NRCS Idaho Snow Survey web page.
