Two man-made wetland complexes are found on the KDWP Clinton Wildlife Area. The oldest is the Coblentz Marsh Complex, which consists of the original West Coblentz marsh and the more recent East Coblentz marsh totaling around 160 acres. These are located on the north side of the Wakarusa River and immediately east of the Shawnee-Douglas county line in Douglas County. The Elk Creek Marsh complex was partially built in 2001 and was filled with water in 2004. It is located on the south side of the Wakarusa River at Boat Ramp #9. The complex consists of 2 completed wetlands and two wetlands under construction. This complex adds around 350 additional wetland acres on the wildlife area and the proposed completion is the Summer of 2006. Both wetlands are filled by pumping water out of the Wakarusa Arm of the lake. Clinton Wildlife Area
