This is a Legacy Assessment. Prior to 2004, assessments were developed under a methodology that pre-dated the Integrated Report guidelines.

Assessment Comments
Assessment is based on results of 1996 IDNR/UHL biocriteria sampling (15 spp., 5 fams.).
Basis for Assessment
The use support status for Class B(CW) aquatic life uses was assessed as not supporting (=NS) based on an analysis and ranking of 9 coldwater stream sites sampled as part of the 1994-1998 stream biocriteria project. The stream reach NW of McIntyre ranked poorest in all 8 indicators used to assess B(CW) use support status. Additional monitoring is needed to determine whether this reach is appropriately designated for Class B(CW) aquatic life uses, and an inventory of possible use impairment causes and sources is also needed.
