Brantley Lake reservoir
Brantley Lake
Brantley Lake in New Mexico is a man-made reservoir created in the 1980s for irrigation and flood control. The reservoir is fed by the Pecos River and surface runoff from surrounding areas. The hydrology of the lake is influenced by the intermittent flows of the Pecos River, and the snowpack from the nearby mountains. The lake provides water for agricultural irrigation, and recreational activities such as fishing, boating, and camping. The reservoir is also a popular spot for bird watching, with over 200 bird species identified in the surrounding area. However, the lake has faced challenges including water quality issues caused by agricultural runoff, and decreased water levels due to drought conditions in the region. Despite these challenges, Brantley Lake remains an important resource for the surrounding communities.

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 Brantley Lake
Where does the data for Brantley 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 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.
