The Dell Creek watershed lies in northeastern Sauk County and southern Juneau County.
Agriculture predominates in the watershed.
Dell Creek State Wildlife Area and Hulbert State Fishery Area are in the watershed. The Wisconsin Dells - Lake Delton tourist area falls partially within this watershed. Intense commercial development pressure continues to have an effect on water resources of the area. The Lake Delton Lake Association and the village of Lake Delton contracted for a lake study and management plan to be developed for Lake Delton. All of Dell Creek in Sauk County has been nominated as exceptional resource waters under the state's antidegradation program.
