About this reservoir

Lk Tahoe A Tahoe City Ca

Lake Tahoe is located in Tahoe City, California, and is the largest alpine lake in North America. The lake was formed over two million years ago and has a surface area of 191 square miles. The lake is fed by 63 streams and rivers, with the largest being the Truckee River. The hydrology of the lake is closely monitored, and the Tahoe Regional Planning Agency regulates development to protect water quality. The snowpack that covers the surrounding mountains provides the majority of the water that feeds the lake. The lake serves as a primary source of drinking water for the surrounding areas and is also a popular recreational destination for activities such as skiing, boating, and fishing. The region is also home to several agricultural operations, including vineyards and orchards.

FAQ

About Lk Tahoe A Tahoe City Ca

Where does the data for Lk Tahoe A Tahoe City 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).
