Sauk River Watershed Stressor Identification Report—Lakes

Document
Description
This report summarizes SID work related to lakes in the Sauk River Watershed (hereafter referred to as the SRW). The SRW encompasses 667,200 acres of land and traverses portions of six counties. Land usage for the SRW is characterized predominantly as cultivated cropland, and includes the cities of Cold Spring, Melrose, Osakis, Richmond, Rockville, Sauk Centre, Waite Park, and portions of St. Cloud. Additionally, the SRW contains numerous lakes, rivers, streams, and wetland complexes.
Within the SRW, 30 lakes were sampled and assessed using the FIBI to evaluate biological health. Of the sampled lakes, nine were assessed as not supporting aquatic life use based on FIBI scores that were below the impairment threshold established for similar lakes. Furthermore, two lakes were considered vulnerable to future impairment based on FIBI scores near the impairment threshold. This report reviews stressor information for the SRW lakes that were either assessed as not supporting aquatic life use or considered vulnerable to future impairment.
