ROCK COUNTY - Boaters will have to take it slow on the Rock River.
The Rock County Sheriff's Office has declared a Slow-No Wake restriction on the Rock River.
According to the U.S. Geological Survey Gauges, the water level at Lake Koshkonong is 8.16 feet and 6.79 feet at Afton. County law dictates the Rock River must have a wake restriction as a result.
Deputies will begin placing slow-no wake signs along the river at all public access points.
