Mackay Res Nr Mackay Id reservoir
Mackay Res Nr Mackay Id
Mackay Reservoir in Idaho was created in 1946 by the construction of Mackay Dam on the Big Lost River. The reservoir has a capacity of 36,200 acre-feet of water and is primarily used for irrigation of agricultural land. The hydrology of the area is influenced by snowpack, which provides water for both the reservoir and the surrounding agricultural land. The reservoir is also used for recreational purposes, including fishing, boating, and camping. The Big Lost River provides water to the reservoir and is a popular destination for fly fishing. The surrounding area is known for its scenic beauty and opportunities for outdoor recreation, including hiking, hunting, and wildlife viewing.

About Mackay Res Nr Mackay Id
Where does the data for Mackay Res Nr Mackay Id 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.
