Mokeler Creek is a 10.1-mile-long (16.3 km)[1] tributary of Piscasaw Creek, itself a tributary of the Kishwaukee River, in northern Illinois.[2]


Mokeler Creek originates in farm fields between Crowley Road and Oak Grove Road, about 2.5 miles (4.0 km) northeast of Harvard, Illinois.[3] It then flows directly through the city of Harvard.[3] The creek is a tributary of Piscasaw Creek and flows southwest until it empties into the Piscasaw about 4.4 miles (7.1 km) southwest of Harvard.[3]


Mokeler Creek is 10 stream miles in length.[4] In 1996 the Illinois Environmental Protection Agency assessed the stream for overall resource quality.[4] It was found to have "fair" conditions, with the main contamination problems coming from agricultural run-off and construction.[4] Additionally, the City of Harvard's wastewater treatment plant discharges effluent into Mokeler creek as it flows through the City.
