The presumptive Class A1 (primary contact recreation) uses remain "not assessed" due to the lack of information upon which to base an assessment. The Class B(WW2) aquatic life uses remain assessed as "partially supported" based on results of biological monitoring and habitat assessment conducted as part of the DNR stream use assessment in September 1994. Although the data upon which this assessment were originally based have aged well beyond 10 years--and are thus considered too old to characterize current water quality conditions--the indication of a potential impairment suggests that this stream segment should remain assessed (evaluated) as "partially supported" and thus remain in Category 3b of Iowa’s Integrated Reports (i.e., on Iowa's list of waters in need of further investigation). The assessment developed for the 2004 assessment/listing cycle is included below.
Continue to use the assessment developed for the 1998 and 2000 reporting cycles that was based on results of the 1994 DNR stream use assessment. As stated in the assessment developed for the 1998 reporting cycle, the aquatic life uses were assessed as "partially supported” due to (1) presence of a relatively depauperate fish community (7 species from 2 families) for streams in the Des Moines Lobe subecoregion, (2) presence of less than a majority of the expected fish taxa (4 of 11) for streams in this subregion, and (3) indications on the field sheet of extensive channel alterations due to channelization and generally poor quality aquatic habitats. Follow-up monitoring was recommended to determine the status of the aquatic communities and habitats of this stream and to determine the degree to which the aquatic life uses may be impaired. Follow-up monitoring is needed in this stream reach to determine the status of aquatic communities and habitats and to determine the degree to which the Class B(LR) uses may be impaired. Although the data upon which this assessment were originally based have aged well beyond 10 years--and are thus considered too old to characterize current water quality conditions--the indication of a potential impairment suggests that this stream segment should remain assessed (evaluated) as "partially supported" and thus remain in Category 3b of Iowa’s Integrated Reports (i.e., on Iowa's list of waters in need of further investigation). The assessment developed for the 2004 assessment/listing cycle is included below.
