The river is fed by various tributaries, including the Crawfish River, the Bark River, and the Kishwaukee River. There are several dams along the river, including the Indianford Dam and the Fort Atkinson Dam. The flow of the river is affected by seasonal trends, with higher flows typically occurring in the spring due to snowmelt and rain. The hydrology of the Rock River is interesting, as it has a history of flooding and has been the subject of various flood control projects. Despite this, the river remains an important source of water for communities along its path.
