About this reservoir

Jemez Canyon Reservoir

Jemez Canyon Reservoir is a man-made lake located in the Jemez Mountains of New Mexico. The reservoir was created in 1957 by the construction of a dam across the Jemez River. The hydrology of the area is dominated by monsoon rains and snowpack melt. In particular, the Valles Caldera National Preserve is an important surface flow provider to the reservoir, as well as the surrounding snowpack.

The reservoir is primarily used for irrigation purposes, providing water to the surrounding agricultural communities. Additionally, the reservoir is a popular recreational destination for fishing, boating, and camping. The Jemez Canyon area is rich in cultural history, with evidence of human habitation dating back over 10,000 years. Today, the area is managed by the US Forest Service and is an important natural resource for the region.

FAQ

About Jemez Canyon Reservoir

Where does the data for Jemez Canyon 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 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.
