Basis for Assessment

[Note: For the 2002 report, the previous waterbody segment IA 01-WPS-0190-2, which extended 28 miles from the upper end of Sweet Marsh to an unnamed tributary in Chickasaw County, was split into four subsegments: (1) from the upper end of Sweet March Segment C to the Bremer/Chickasaw Co. line (IA 01-WPS-0190-2), (2) from the Chickasaw/Bremer line to unnamed tributary N of Frederickburg (IA 01-WPS-0190-3), (3) from unnamed tributary north of Frederickburg to Plum Cr. (IA 01-WPS-0190-4), and (4) from Plum Cr. to unnamed tributary north of New Hampton (IA 01-WPS-0190-5). See the assessment information for the original 28-mile waterbody segment (IA 01-WPS-0190-0) under segment IA 01-WPS-190_2.]

SUMMARY: The Class B(LR) aquatic life uses are "not assessed." EXPLANATION: The information upon which the previous assessment was based was collected in 1995 (see above); these data are now considered too old (greater than five years) for accurately characterizing current water quality conditions. Thus, support of the aquatic life uses was changed to "not assessed."
