Officials at Clinton Wildlife Area say illegal off-road drivers are causing damage around Clinton Lake that has forced the closure of some roads.

The Lawrence Journal-World reports the Rock Creek Boat Ramp on the southwest side of the lake and portions of Green Road on the wildlife area’s western edge were closed because of damage.

Justin Hamilton with the Kansas Department of Wildlife and Parks says potholes and ruts have developed because of the damage, making some pathways unnavigable.

He says some areas around Douglas State Fishing Lake near Baldwin City also were damaged recently by off-road driving, and there have been issues with people driving in muddy fields after crops have been harvested.
