Santa Rosa Reservoir reservoir
As of July 15, 2026, Santa Rosa Reservoir is holding 40,112 acre-ft of water — 76% of normal storage for this date. Storage data refreshed throughout the day.
Santa Rosa Reservoir
Santa Rosa Reservoir is a man-made lake located on the Pecos River in eastern New Mexico. Built in the 1980s, the reservoir was created for flood control, irrigation, and recreational purposes. It has a capacity of 117,000 acre-feet of water and a surface area of 3,800 acres. The reservoir receives water from the Pecos River, which is fed by several tributaries and snowpack in the Sangre de Cristo Mountains. The reservoir provides water for irrigation to surrounding agricultural land, as well as for recreational activities like fishing and boating. The Pecos River also serves as a source of hydroelectric power. The reservoir is managed by the United States Army Corps of Engineers and is an important part of the water supply infrastructure in the region.

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.

About Santa Rosa Reservoir
Where does the data for Santa Rosa 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.
