Water Quality
There is limited water quality data for Willow Creek. From 1977 to 1989, the District monitored stream water quality at the junction of Willow Creek and Kohlman Creek to assess the quality of water discharged to Kohlman Lake. The 1997 RWMWD Plan stated that dissolved oxygen, pH, temperature and fecal coliform counts all met then‑current MPCA standards, with some increases in fecal coliform counts during a rapid urbanization period of 1984 to 1989. Suspended solids and turbidity also generally met MPCA standards during this monitoring period. Stream water quality monitoring at the Ditch 18 location was discontinued after the 1990 evaluation.
