Documentation
Assessment Comments
Assessment is based on result of the October 1995 IDNR Stream Use Assessment conducted upstream from Ida Grove, Ida county.
Basis for Assessment
Used results of DNR stream assessment in October 1995 to assess support of the Class B(WW) aquatic life uses as PS due to (1) habitat score (17) much worse than overall average median score for DNR stream use assessments (most impact due to extensive channelization, lack of pool development, and extensive areas of eroding streambanks), (2) fish score (10) worse than 75th percentile score (12) for assessments made with electrofishing equipment.
