Assessment Comments

Assessment is based on (1) IDNR ambient city monitoring upstream form Mason City and (2) two water quality studies conducted for Lehigh Cement Co. in 1994-95.

Basis for Assessment

See assessment developed for the downstream waterbody subsegment of the Winnebago River (IA 02-WIN-0010-1).  Follow-up monitoring is needed to determine the status of the aquatic communities of this reach of the Winnebago River.  Any impacts are likely located in the vicinity of the Mason City urban/industrial area.
