About this reservoir

Greenwood Reservoir Near Greenwood

Greenwood Reservoir is a man-made body of water located in the Upper Peninsula of Michigan near the town of Greenwood. The reservoir was created in the 1930s as part of the Greenwood Hydroelectric Project, which provides hydroelectric power to the surrounding areas. The reservoir is fed by both surface flow and snowpack, with the majority of the water coming from snowmelt in the spring. The reservoir is used for a variety of recreational activities, including fishing, boating, and camping. The surrounding area is largely agricultural, with farms and fields dominating the landscape. The reservoir and its surrounding lands are owned and managed by the U.S. Forest Service, which works to maintain the area's natural beauty and protect its valuable resources.

FAQ

About Greenwood Reservoir Near Greenwood

Where does the data for Greenwood Reservoir Near Greenwood 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.
