Lake Powell At Glen Canyon Dam reservoir
Lake Powell At Glen Canyon Dam
Lake Powell is a reservoir formed by the Glen Canyon Dam in Arizona. The dam was completed in 1963 and created Lake Powell, which is a popular recreational area. The hydrology of the area is mainly influenced by the Colorado River, which flows into the lake. Snowpack in the surrounding mountains also contributes to the surface flow into the lake. The lake provides water for irrigation and is also used for recreational activities such as boating and fishing. The area also has a rich history, with the Glen Canyon Dam being built as part of the Colorado River Storage Project, a large-scale water management system in the western United States. Despite controversy surrounding the dam's construction and environmental impacts, Lake Powell remains a popular tourist destination.

About Lake Powell At Glen Canyon Dam
Where does the data for Lake Powell At Glen Canyon Dam 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.
