About this reservoir

Hamilton Lake At Hamilton

Hamilton Lake in Indiana was created in 1837 as a result of a dam being built on the headwaters of the Wabash River. The lake covers 800 acres and has an average depth of 25 feet. It is supplied by a combination of surface flow and snowpack from the surrounding area. The lake is a popular destination for recreational activities such as swimming, boating, and fishing. Agricultural uses include irrigation for nearby crops. In recent years, a focus has been put on improving the water quality of the lake through measures such as controlling nutrient runoff from surrounding farms. The lake is also home to a variety of wildlife, including fish, waterfowl, and turtles.

Plan around the weather

Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

FAQ

About Hamilton Lake At Hamilton

Where does the data for Hamilton Lake At Hamilton 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 below 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.
