Assessment Comments

Stream use assessment in Fayette County.

Basis for Assessment

Used a review of the field sheet from the October 1991 DNR stream use assessment in Fayette County to  continue to assess support of the Class B(LR) aquatic life  uses as PS due to (1) presence of less than a majority of the expected fish taxa (5 of 11) for streams in the Iowan Surface  subecoregion, (2) indications on field sheet of frequent  channel alterations from channelization and pasturing of the  riparian corridor, and (3) notes on field sheet that stream is  "very muddy and shallow."  Although the condition of the aquatic  community and aquatic habitats in the reach assessed suggest  partial support of the Class B(LR) uses, this assessment was  conducted within one-half mile of the upstream boundary of the  Class B(LR) reach.   Follow-up monitoring is needed to determine  the status of the aquatic communities and habitats--both at  the 1991 assessment site and further downstream in the Class  B(LR) reach--and to determine the degree to which the Class B(LR)  uses may be impaired.
