About this reservoir

Stony Lake Near Washington

Stony Lake is a small lake located near Washington, MI in Michigan that has an interesting history. Originally, it was a wetland that was formed by a glacier during the Ice Age. Later, it was formed into a lake as a result of human intervention. The lake has a unique hydrology system which is supplied by specific surface flow and snowpack providers. The primary surface flow provider is the Clinton River, while the primary snowpack provider is the surrounding land. Agriculture is not a significant factor in the area, but the lake is known for its recreational uses. It is a popular spot for fishing, boating, and swimming. There are also several parks and trails in the area that provide opportunities for hiking and biking. Overall, Stony Lake is a valuable resource for both the environment and the community.

FAQ

About Stony Lake Near Washington

Where does the data for Stony Lake Near Washington 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.
