The Cedar Creek watershed is a 330 km² sub-basin of the larger Milwaukee River watershed. Cedar Creek originates from Big Cedar Lake in the Town of West Bend and flows east into Little Cedar Lake. It then flows east through Jackson before turning south, crossing State Highway 60 where there is a USGS gauge and briefly flows through Grafton before entering Cedarburg's north side. The creek flows through downtown Cedarburg, and empties into the Milwaukee River southeast of Cedarburg in the Town of Grafton. The lower section through Cedarburg is notable for its the steep slope, and early settlers made use of this by building several mills and accompanying dams.
