About this reservoir

Topaz Lk Nr Topaz

Topaz Lake is a reservoir located in Douglas County, Nevada, close to the California border. The lake was created in 1922 with the construction of the Topaz Lake Dam. The area is known for its natural beauty and offers a range of recreational activities, including fishing, boating, camping, and hiking. The lake's hydrology is primarily supplied by the West Walker River, East Walker River, and other mountain streams. The lake's water level is affected by snowpack, which is provided by the Sierra Nevada Mountains. The area is also used for agricultural purposes, including hay and cattle ranching. Despite being a popular recreational area, Topaz Lake was also historically significant as it was used as a trading hub for Native Americans and early settlers.

FAQ

About Topaz Lk Nr Topaz

Where does the data for Topaz Lk Nr Topaz 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).
