As of Tuesday, March 6, 2018
Regional snowpack levels are above average, according to the latest water supply outlook report from the Natural Resources Conservation Service.
Currently, the highest snowpacks are in the Clearwater Basin where, collectively, they are 110 percent of normal.
Precipitation since the water year started on Oct. 1, 2017, varies across the state with watersheds ranging from 70 to 130 percent of normal.
“A winter like this one is what makes Idaho unique and interesting,” said Ron Abramovich, Water Supply Specialist with the Idaho Natural Resources Conservation Service. “The weather pattern has been pretty consistent since October, with the jet stream streaking across northern Idaho and then dipping along the Continental Divide. This brings moisture to the basins north of the Salmon River, while central and southern Idaho are drier than normal.”
“With more than half the winter behind us, many reservoir operators are taking a wait-and-see approach toward releasing water,” Abramovich said. “Good reservoir storage will provide a buffer if snowpacks remain below normal across southern Idaho.”
