Rush Creek is a 14.9-mile-long (24.0 km) [1] tributary of the Kishwaukee River in northern Illinois. [2] [3]
There is another Rush Creek that is a tributary of the Mississippi River in Carroll County. [4]
Rush Creek's origin is in a complex of wetlands near Harvard, Illinois, two miles southeast. [5] The stream then flows southwest until it empties into the main stem of the Kishwaukee River one mile east of Garden Prairie. [5]
Approximately 65% of the main stem of Rush Creek has been channelized (ditched and straighten), however 50% of those areas are showing signs of recovery. [5] Despite the channelization and encroachment from agriculture many of the stream's features such as riffles can still be seen. [5]
Twenty-nine species of fish have been identified within Rush Creek and its tributaries, two of those species have not been seen in the watershed since 1965 - the northern pike and the largescale stoneroller. [5] Three animal species are on state or federal endangered or threatened lists - river otter, and two mussels, Elliptio dilatata (Spike) and Alasmidonta viridis (Slippershell). [5]
