About this reservoir

Big Chapman Lake Near Warsaw Ind

Big Chapman Lake is a popular recreational lake located near Warsaw, Indiana. The lake was created in the 1960s by damming Chapman Creek, and it covers 630 acres with a maximum depth of 44 feet. The hydrology of the lake is influenced by precipitation, runoff, and groundwater, and specific surface flow is provided by Chapman Creek. Snowpack also contributes to the water levels in the lake during the winter months. The lake is used for a variety of recreational activities such as fishing, boating, and swimming. Agriculture also contributes to the lake's water quality, as runoff from nearby farms can affect the lake's nutrient levels. The lake is managed by the Big Chapman Lake Property Owners Association, which oversees water quality and safety measures.

FAQ

About Big Chapman Lake Near Warsaw Ind

Where does the data for Big Chapman Lake Near Warsaw Ind 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).
