About this reservoir

Lahontan Reservoir Nr Fallon

Lahontan Reservoir is a man-made lake located in Nevada, near the town of Fallon. The reservoir was created in 1905 as part of an irrigation project aimed at providing water to the surrounding agricultural land. The lake is fed by the Carson and Truckee Rivers and its size can vary depending on the snowpack levels in the surrounding mountains. The reservoir provides water for irrigation, recreation, and serves as a habitat for fish and wildlife. The Lahontan Reservoir is a popular destination for boating, fishing, and camping. The surface flow from the Carson and Truckee rivers is critical to the reservoir's water levels, and the snowpack in the surrounding mountains plays a significant role in determining the amount of water available for use.

FAQ

About Lahontan Reservoir Nr Fallon

Where does the data for Lahontan Reservoir Nr Fallon 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).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this reservoir, set a threshold, and you'll get a push the moment conditions cross.
