The Rock County Sheriff’s Office reports the U.S. Geological Survey Gauge for the water level on Lake Koshkonong is at 8.05feet. County ordinance requires slow-no-wake speed restrictions be placed along the river when water levels top eight-feet. Signs will be posted at all public access points between the northern Rock County line and the Indianford Dam. Earlier this week the water level topped 6.5 feet at Afton prompting slow-no-wake restrictions between the Indianford Dam and the West B R Townline Road Bridge.
