About

Designated Water Trail status protects 182 miles of the Rock River through an extensive network of municipal access points and county parks. At 394 CFS average flow (optimal range 200–600), the river connects dozens of communities through managed sections from Waupun County Park downstream to multiple Riverside Park locations. USGS gauge 05424057 tracks conditions for paddlers navigating the system. The water trail designation ensures coordinated access through parks like Heritage Park, Tanner Park, Blue Heron Landing, and Harnischfeger County Park, with put-ins and take-outs spaced for day trips or longer expeditions. Municipal partnerships maintain facilities at locations including Clausing Bowling Green Park, Kiwanis Park, and Rotary Waterfront Park, creating a paddling corridor that spans multiple counties and jurisdictions.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
