Rock River is on the rise, slow/no-wake restrictions imposed
JANESVILLE—Rock County sheriff's deputies are placing slow/no-wake signs at public access points along the Rock River in the southern half of Rock County today.
The posting means the river's entire run in Rock County is under the restriction.
The northern portion—from the Beloit Rock Town Line Road Bridge to Lake Koshkonong—has been slow/no wake since March 31
The addition comes because the water level has risen. County ordinances require a slow/no-wake speed restriction south of the bridge when the U.S. Geological Survey gauge at Afton exceeds 8.5 feet.
The National Weather Service predicts the water level at Afton will peak at 8.9 feet Wednesday morning. Minor flooding is expected when the gauge reaches 9 feet.
Lake Koshkonong itself does not fall under the slow/no-wake orders.
