According to US Geological Survey Gauges, the water level for Lake Koshkonong is 8.02 feet. County Ordinance requires a slow-no-wake speed restriction be placed on the Rock River when water levels exceed 8.0 feet on Lake Koshkonong.

The Sheriff’s Office is providing public notice of the Rock River’s current slow-no-wake status. Deputies will begin placing slow-no-wake signs along the river at all public access points. The slow-no-wake restriction will now be in affect from the northern Rock County line downstream to the W B-R Townline Road Bridge.

County Ordinance requires a slow-no-wake speed restriction on any portion of the Rock River downstream from West B-R Townline Road Bridge to the southern Rock County line when the water levels exceed 8.5 ft. The water level has not exceeded 8.5 ft in this portion of the Rock River; therefore, West B-R Townline Bridge to the southern Rock County line, along with Lake Koshkonong will not be restricted to the slow-no-wake speed restriction.
