Assessment Comments

Insufficient information available to develop an assessment. Previous assessment was based on results of an IDNR stream use assessment conducted in October 1994 in O'Brien County.

Basis for Assessment

SUMMARY: The Class B(LR) aquatic life uses are considered "not assessed" due to the age of the biological data upon which the previous assessments of these uses ("fully supported") were based.

EXPLANATION: The 2004 assessment for this stream segment was based on results of biological monitoring conducted as part of an IDNR stream use assessment in 1994. Because the data upon which this assessment was originally based have aged beyond 10 years--and are thus considered too old to characterize current water quality conditions--the Class B(LR) uses of this segment are now considered "not assessed". Thus, this stream segment is moved from IR Category 1 to 3a (insufficient information to assess any uses).
