Mountain Meadows Reservoir
As of July 17, 2026, Mountain Meadows is holding 14,311 acre-ft of water — 77% of normal storage for this date. Storage data refreshed throughout the day.
Mountain Meadows
Mountain meadows in California are unique ecosystems that provide critical hydrological functions such as water storage, filtration, and release. These meadows are also important habitat for a variety of wildlife and plants. Historically, many of these meadows were used for agriculture and grazing, which often resulted in significant degradation. However, efforts are now underway to restore these important ecosystems.
The hydrology of mountain meadows is complex, with specific surface flow and snowpack providers contributing to the water supply. Snowpack provides a large portion of the water in the spring and summer, while specific surface flow occurs when groundwater discharges onto the surface, resulting in the formation of a stream.
Agricultural uses of mountain meadows have decreased in recent years, but some grazing still occurs. Recreational uses include hiking, fishing, and wildlife viewing. Overall, mountain meadows are important ecosystems that provide essential hydrological functions and habitat for wildlife.

About Mountain Meadows
Where does the data for Mountain Meadows 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 below 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.
