South Beaver Creek IA 02-CED-561
mouth (S25 T90N R17W Butler Co.) to confluence with Middle Fork South Beaver Cr. in S28T89R17W Grundy Co.
Assessment Comments
Assessment based on 1996 biocriteria monitoring.
Basis for Assessment
[This subsegment was created in 1998 due to monitoring results that indicated a different aquatic life use assessment from that based on a 1992 DNR stream use assessment conducted approximately 2 stream miles upstream from the confluence with the N. Fk. of S. Beaver Cr. (see assessment for S. Beaver Cr., Subsegment 2).] Used results of the DNR biocriteria monitoring conducted in Grundy County in July 1996 approximately 2.5 mi SW of Parkersburg to assess support of the Class B(LR) aquatic life uses as FS. This sampling showed a relatively diverse fish community of 17 species from 5 families that contained nearly all (10 of 11) of the expected fish taxa. No violations of Class B(LR) water quality criteria occurred in the sample collected during biocriteria sampling.
