About this reservoir

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.

Modelled bathymetry

Inside the reservoir

The real shoreline of this water body, with a depth model scaled so the basin holds exactly its recorded storage. Drag to orbit, scroll to zoom, and use the slider to drain and refill it. Click anywhere on the basin for the modelled depth there.

How this is built. The shoreline is the National Hydrography Dataset polygon for this water body (“Mountain Meadows Reservoir”), matched to the dam by proximity and confirmed by comparing its area with the National Inventory of Dams surface area. Depth is modelled, not surveyed: the basin is shaped by distance from shore — deep in open water, shallow in the bays — and scaled so its volume equals the recorded storage. No national bathymetric survey exists for US reservoirs. Treat the shoreline, area and volume as measured, and the depth distribution as an informed approximation.

Above normal pool, water is shown rising within the normal-pool shoreline. Where it would actually spread depends on the surrounding terrain, which is not modelled here — a reservoir in a steep canyon barely widens, one on flat ground can spread a long way. This is a depth and volume figure, not an inundation map. Official inundation mapping for a dam comes from its Emergency Action Plan.

FAQ

About Mountain Meadows

What is the water level at Mountain Meadows Reservoir right now?

The most recent report for Mountain Meadows Reservoir is from July 10, 2024; no newer reading has been published. Daily levels and the year-over-year trend are shown on this page.

Is Mountain Meadows Reservoir high or low right now?

Compare the percent-of-normal figure on this page: above 100% means storage is higher than the historical average for the date (a wet year), below 100% means lower (a dry year or drought). The daily-levels chart shows the current trend.

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.
