Martis Creek Reservoir reservoir
As of July 16, 2026, Martis Creek Reservoir is holding 873 acre-ft of water — 95% of normal storage for this date. Storage data refreshed throughout the day.
Martis Creek Reservoir
Martis Creek Reservoir is located in Placer County, California, and was completed in 1972. The reservoir is situated at an elevation of 5848 feet and has a capacity of 23,000-acre feet. It serves as a storage facility for the Martis Creek Watershed, which includes Martis Creek and its tributaries. The reservoir is primarily fed by snowmelt and surface flow from Martis Creek, as well as the surrounding snowpack.
The Martis Creek Reservoir is an essential source of water for irrigation and agricultural purposes in the area. Additionally, it also supports recreational activities, including fishing, boating, and hiking. The reservoir has an extensive network of trails that offer stunning views of the surrounding scenery. As a result, it attracts numerous visitors every year, making it a vital economic resource for the region.

About Martis Creek Reservoir
Where does the data for Martis Creek Reservoir 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.
