About this reservoir

Echo Lake

Echo Lake is a small alpine lake located in the Sierra Nevada mountains of California. The lake has a long history of recreational use, with the Echo Chalet resort opening in the early 1900s. The lake serves as an important source of water for the surrounding areas, with its hydrology primarily fed by surface flow and snowpack melt. The Upper American River Project manages the reservoir and dam, which provides hydroelectric power to the area. The lake also serves as a popular destination for outdoor enthusiasts, with activities such as fishing, camping, and hiking available. The surrounding forests are home to a variety of wildlife, including black bears, coyotes, and mule deer. Agriculture in the area includes small-scale farming and ranching, while the lake also supports recreational activities such as swimming and boating.

Plan around the weather

Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

FAQ

About Echo Lake

Where does the data for Echo Lake 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.
