Shell Rock River Watershed Stressor Identification Report—Lakes

This report summarizes SID work related to lakes in the Shell Rock River Watershed (SRRW). In total, the SRRW encompasses over 157,000 acres in southern Minnesota and 533,000 acres in northern Iowa. The SRRW is included in the in the broader Upper Mississippi-Iowa-Skunk-Wapsipinicon Basin. This report focuses on the Minnesota portion of the Shell Rock River Watershed (hereafter referred to as the SRRW), which is located within the Western Corn Belt Plains ecoregion and is characterized predominantly as cultivated agricultural land. The SRRW contains several cities, including Albert Lea, Glenville, Twin Lakes, Hayward, and Manchester. Several of the larger waterbodies include Albert Lea, Fountain, and Pickerel lakes. Of the lakes within the SRRW, only Fountain Lake was sampled and assessed to evaluate biological health. Fountain Lake was assessed as not supporting aquatic life use based on FIBI scores that were below the impairment threshold established for similar shallow lakes. Other lakes within the SRRW were either too small or experienced recent significant winterkill events that made them unsuitable to be assessed using FIBI methods. The remainder of this document reviews stressor information for the SRRW and Fountain Lake specifically.
