Crooked Creek is an urban stream that originates in southern Hamilton County, flows southerly through Pike and Washington Townships in Marion County, and discharges into the White River through Lake Sullivan, a lake dredged from a large wetland complex in northwest Center Township in Indianapolis, Indiana. The Crooked Creek watershed drains an area of approximately 20 square miles and includes well established residential areas, highly intensive commercial uses, both light and heavy industry, and land in agricultural use, most of which is expected to be developed in the coming years. Crooked Creek has been dredged periodically and is degraded by urbanization. Water quality problems include heavy sediment loads from uncontrolled construction sites, septic effluents, the discharge of raw sewage from surcharging sewers during moderate rainfalls, and nonpoint source pollutants such as pesticides, fertilizers, and petroleum products that enter the creek in stormwater runoff. Flooding also is a problem in the watershed. More than 100 homes are located in the 100-year floodplain, and floods of record have resulted in significant damages.
