Cast Gill

Cast Gill is an independent reference site providing detailed facts about Wisconsin's lakes, drawing on public data from the Wisconsin DNR, USGS, Water Quality Portal, GBIF and the National Weather Service. Users can search by lake, county or fish species to find size, depth, water clarity, stocking information, boat landings and links to official fishing regulations. The site covers 6,133 lakes and 182 fish species, and includes an interactive map, a county browser, and a trip card feature for sharing forecasts with friends. Each data point shows its source and update date. The site is not affiliated with the Wisconsin DNR and recommends checking official regulations before fishing.
