About this reservoir

Costilla Reservoir Near Costilla

Costilla Reservoir is located in Costilla, New Mexico and was completed in 1969. The reservoir has a storage capacity of 10,000 acre-feet and is supplied by the Costilla Creek. The reservoir is managed by the Costilla Irrigation District for agricultural purposes, with the water being used for irrigation of crops like alfalfa, oats, and corn. The reservoir is also used for recreational purposes, including fishing, camping, and boating. Surface flow is greatly influenced by the snowpack in the surrounding mountains, with snowmelt contributing to the reservoir's water levels. The surrounding area is known for its scenic beauty and diverse wildlife, including elk, deer, and eagles.

FAQ

About Costilla Reservoir Near Costilla

Where does the data for Costilla Reservoir Near Costilla 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 above 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.
