The west fork, at 439 kilometers (273 miles), is the longest fork of the river. It starts in rural Winchester in Randolph County, winds through Muncie, Anderson and Indianapolis before joining the east fork in Daviess County. The east fork starts in Columbus at the confluence of the Driftwood and Flatrock rivers. The east fork travels 261 kilometers (162 miles) before merging with the west fork. The combined White River then flows another 72 kilometers (45 miles) before draining into the Wabash river at the Indiana-Illinois border. The total White River basin watershed is 14882 square kilometers (5,746 square miles). Pollution In 1997, the White River was listed as one of the United States' most threatened rivers. Pesticides (herbicides and insecticides) are used extensively in the White River basin. Application of herbicides to corn and soybeans accounts for most of the use. The pesticides most frequently detected near the mouth of the White River during 1991 - 1995 were the herbicides alachlor, atrazine, cyanazine and metolachlor. The highest concentrations of herbicides in the river were typically found during late spring runoff following application. Generally, concentrations of alachlor have been decreasing while concentrations of acetochlor have been increasing in response to changes in the use of these herbicides in the basin. The total amount of the commonly used herbicides transported by the river is about 1 percent or less of the amount applied to cropland. Insecticides commonly used in urban and agricultural areas also were found but in much lower concentrations than commonly used herbicides. Trivia - The headwaters of the west fork are farther east than the east fork
