About this reservoir

Milner Lake At Milner Dam Id

Milner Lake is located in south-central Idaho at Milner Dam, which was constructed in 1904. The lake covers an area of 1,430 acres and has a maximum depth of 25 feet. Milner Lake serves as a critical water source for irrigation and hydroelectric power generation in the region. The surface flow providers include the Snake River, which enters the reservoir at the southern end, and the Big Wood River, which enters from the east. The snowpack providers include the Smoky Mountains to the east and the Sawtooth Mountains to the north. The lake is primarily used for agricultural irrigation and provides water to approximately 50,000 acres of farmland. It is also popular for recreational activities such as fishing, boating, and swimming.

FAQ

About Milner Lake At Milner Dam Id

Where does the data for Milner Lake At Milner Dam Id 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.
