California & Nevada Drought map has changed

The storms that have hit northern California and Nevada during the last 6 weeks have changed the drought map dramatically from earlier in the winter. Rain in northern California has filled reservoirs and sent rivers flooding for the first time since 2005 in several areas in both northern California and Nevada – including the Truckee Continue Reading »

Truckee River Flood Crest Reached in Truckee Meadows

Flood waters in the Truckee River appear to have crested in downtown Reno earlier this morning (1-9-2017).

Anticipating winter snows for Truckee River flows

Despite the rains of October in the central Sierra, Tahoe today is still 3.6″ below its rim and no water flows to the Truckee River from the Lake.  Most of the Truckee River flow comes from tributaries downstream of Lake Tahoe’s outlet including the Little Truckee River, its largest tributary. It is, however, likely that Tahoe will rise above Continue Reading »
