Guadalupe Reservoir reservoir
Guadalupe Reservoir
Guadalupe Reservoir in California was constructed in 1959 and is located in the Santa Cruz Mountains. The reservoir is fed by the Guadalupe Creek and is a part of the Santa Clara Valley Water District's water supply system. The hydrology of the reservoir is largely dependent on surface flow from the creek and snowpack providers in the surrounding mountains. The reservoir provides water for agricultural and recreational purposes, including irrigation and fishing. However, due to the ongoing drought in California, the water level in the reservoir has been lower than usual, affecting its ability to meet the water needs of the surrounding communities. Additionally, the reservoir has experienced issues with algae blooms and contamination in recent years, leading to temporary closures for recreational use.

About Guadalupe Reservoir
Where does the data for Guadalupe 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.
