Heron Reservoir reservoir
Heron Reservoir
Heron Reservoir in New Mexico was created in 1971 and is located in the San Juan Mountains. It is a man-made lake that was built to provide water for irrigation, municipal use, and recreation. The reservoir is fed by several streams and rivers, including the Rio Chama and Willow Creek, which are important sources of surface flow. The area also receives significant snowpack that contributes to the reservoir's water supply. The reservoir is managed by the Bureau of Reclamation and is used for recreational activities such as fishing, boating, and camping. Additionally, the reservoir provides water to irrigate farmland in the surrounding area, particularly for alfalfa and hay production.

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 Heron Reservoir
Where does the data for Heron 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.
