Dutch Hollow Lake is a man-made reservoir located in the city of La Valle (Sauk County) Wisconsin U.S. Created by developers in the 1970s by impounding the water of Dutch Hollow Creek it is now a public-access lake regulated by the Wisconsin Department of Natural Resources with two public-access ramps. The 40-foot (12 m) depth of the lake is maintained both by the flow from Dutch Hollow Creek and the pumping of groundwater.
