As we approach the traditional “peak” snowpack date near the end of the month, the Sierra Nevada snowpack is going to end the year just over half of average – around 55%, says USDA meteorologist Brad Rippey. “We have a 15 inch snowpack – if you melt all of the water in that snow. Typically, we’d like to get closer to 30 inches in a normal year.” Rippey told USDA Radio. “So, a very disappointing year for the Sierra Nevada snowpack watershed.”
Rippey said the winter wet season of 2021-22 “started with a bang in October and another round of significant precipitation in December, but the other months have been drier than average. This is the third consecutive year - 8 of the last 11 - with below average winter accumulation of snow “so that will result in some necessary cutbacks of allocations.”
