About this reservoir

Donner Lk Nr Truckee Ca

Donner Lake is located near Truckee, California, and is a popular recreational area for swimming, fishing, and boating. The lake was named after the Donner party, a group of pioneers who became stranded in the area during the winter of 1846-1847. The hydrology of the area is influenced by the surrounding mountains, which feed snowmelt into the lake. The snowpack providers include the Sierra Nevada range, which receives significant amounts of precipitation during the winter months. The lake is also used for irrigation and agricultural purposes, with water being diverted from the Truckee River. Overall, Donner Lake is a popular destination for outdoor enthusiasts and provides a vital water source for the surrounding areas.

FAQ

About Donner Lk Nr Truckee Ca

Where does the data for Donner Lk Nr Truckee Ca come from?

Daily storage, pool elevation, and release rates are sourced from USGS, USBR, and USACE monitoring stations. Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

Storage observations are updated daily by the operating agency. The 15-day weather forecast refreshes throughout the day. Snoflo caches and renders the most recent observation -- check the "as of" timestamp on the storage card.

What does the Hazard hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
