About the sangamon river

The Sangamon River is a 246-mile-long tributary of the Illinois River. The river has a rich history, having been used by Native Americans for hunting and fishing. The river was also an important transportation route in the 19th century, with steamboats and barges carrying goods up and down the river.

The river's hydrology is influenced by several reservoirs and dams, including the Sangchris Lake Dam and the Lake Decatur Dam. These structures help regulate the river's flow and provide water for municipal and agricultural use.

Recreational activities on the Sangamon River include fishing, boating, and swimming. The river is also popular for hiking and camping, with several state parks located along its banks.

Agricultural use of the Sangamon River is significant, with farmers using the river's water for irrigation and livestock watering. However, agricultural runoff can also pose a threat to the river's water quality, leading to issues such as nutrient pollution and algal blooms.
