About this reservoir

Stillwater Reservoir Nr Beaver River Ny

Stillwater Reservoir is located in the Adirondack Mountains of New York and was created in the 1920s by the construction of a dam on the Beaver River. The reservoir is used for hydroelectric power generation and flood control. The hydrology of the reservoir is dependent on the surrounding snowpack and precipitation, with the largest inflows coming from the Beaver River and its tributaries. The reservoir is also used for recreational activities such as fishing, boating, and camping. The surrounding area is primarily forested and there are no significant agricultural uses in the immediate vicinity. The reservoir is managed by the New York State Department of Environmental Conservation and is part of the Adirondack Park, a protected area of over 6 million acres.

FAQ

About Stillwater Reservoir Nr Beaver River Ny

Where does the data for Stillwater Reservoir Nr Beaver River Ny 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.
