Drought persists: Dry January and February

Dry ground on Peavine Mtn

Deficit of rain and snow continues into March.

Hope for a “jubilant” January, a “fabulous” February, and a “miracle” March fell flat this year. The western US, including much of California and Nevada, faces another drought year. The Drought Monitor map shows the Sierra Nevada in “severe drought” along with all of western Nevada. Worse designations of “extreme” and “exceptional” drought categories are found in portions of 8 of the 9 western states.

Truckee River: low flows ahead for spring and summer

After the summer of 2021’s extreme fires and, in much of the west, unprecedented heat, December’s storms seemed to herald an above average water year in the offing for the Sierra. But a record breaking, dry January and February ended the hope that the 200% snow pack would persist. The ides of March has come and gone. Yet, the Sierra snowpack that supports the Truckee River is just 76 and 68 percent of average in the Truckee River and Tahoe watershed today. Lake Tahoe is just 12″ above its natural rim and the very real prospect of a continuing dry spring mean lower flows into the Truckee River below Tahoe City. The traditional April 1 peak snowpack measurement becomes less relevant as climate change warms temperatures winter and summer. The lack of storms in what should be the Sierra “wet season” stretches our multi-decadal drought for yet a further spring and summer.

About Dennis Ghiglieri

My concern for the Truckee River grew over the years. It started with picking up trash and supporting better water quality. I helped create the "living river"plan with other citizens on the Community Flood Coalition; a plan to reduce flood impacts to infrastructure through river restoration and protection of the floodplain. I understand how critical the Truckee River is to the environment – and economy – of our entire region. I'm hoping that through these pages we can all understand our connection to the Truckee River and why we need to protect it.
