The Cache River is a 92-mile-long river in southern Illinois. It was once a major transportation route for Native Americans and played a crucial role in the development of the region. The Cache River is fed by numerous small streams and is home to a diverse array of aquatic life, including several endangered species. The river is managed by several government agencies, and several reservoirs and dams have been built along its length to regulate its flow and provide irrigation to nearby farms. Recreational opportunities along the Cache River include fishing, boating, hiking, and birdwatching. Agriculturally, the river is an important source of water for local farms, and numerous crops are grown in the region, including corn, soybeans, and wheat. Despite its importance, the Cache River is threatened by pollution, development, and climate change, and efforts are underway to protect and preserve this vital natural resource.
