City of Lino Lakes SWMP | February 8, 2013 Draft | 23 <br /> <br />3.8. Surface W ater R esource s <br />Open water features are a significant land cover type in the City, totaling over 3,000 acres, or roughly <br />14% of the surface area. The largest portion of this cover type (96%) is represented by the large, natural <br />ice block lakes forming the Chain of Lakes a nd other outlier lakes, along with smaller natural ponds. A <br />number of streams and creeks also flow through the City. <br /> <br />Within the municipal boundary of the City of Lino Lakes, seven lakes within the Chain of Lakes <br />(Baldwin, Centerville, George Watch, Marsh an, Peltier, Reshanau, and Rice), Bald Eagle Lake, and two <br />creek reaches (Clearwater and Hardwood) are currently listed on the Minnesota Pollution Control <br />Agency’s 2010 Draft 303d list of impaired waters (Table 4 , Figure 11 ). The eight lakes are listed for <br />nutrient/eutrophication biological indicators affecting aquatic recreation u ses, Clearwater and Hardwood <br />Creeks are listed for fish and/or aquatic macroinvertebrate bioassessments affecting aquatic life, and <br />Hardwood Creek is also listed for dissolved oxygen affecting aquatic life. There are also three lakes that <br />h ave fish consump tion impairments due to high mercury concentrations in fish : Peltier Lake, Otter Lake, <br />and Bald Eagle Lake . In 2009, the MPCA completed a plan to address this mercury impairment. With <br />substantial stakeholder input, the MPCA prepared a plan to reduce mercur y releases in Minnesota. This <br />plan, the Implementation Plan for Minnesota’s Statewide Mercury Total Maximum Daily Load , describes <br />actions Minnesota will take to meet water -quality standards for mercury. <br /> <br />Draft TMDL reports have been written for the eight impaired lakes with nutrient impairments. The public <br />comment period for the Bald Eagle Lake TMDL ended on March 30, 2011; it has not yet been approved <br />by the Environmental Protection Agency (EPA). The publ ic comment period for the TMDL reports for <br />the other seven lakes is from January 30, 2012 through February 29, 2012 . The implementation plans for <br />these impairments will be completed after the EPA approves the TMDLs. <br /> <br />The TMDL for the Clearwater Creek impa irment has not yet been started. It will be part of a future <br />Watershed Restoration and Protection Plan, to be completed by the MPCA in conjunction with local <br />partners. The TMDL for the two impairments on Hardwood Creek is complete and was approved by the <br />E PA on July 10, 2009 (Hardwood Creek Impaired Biota (Fish) and Dissolved Oxygen TMDL can be <br />found on MPCA’s website ). The implementation plan for these two impairments is also complete and was <br />approved by the MPCA in 2009. <br /> <br />There is a TMDL study under way f or bacteria (E. coli and fecal coliform) impairments along portions of <br />the Upper Mississippi River and its tributaries, including Rice Creek. Lino Lakes will be part of that <br />TMDL study. There is also a TMDL underway for Wilkinson Lake as part of the Vadn ais Lakes Area <br />WMO TMDL and Protection Study. <br /> <br />The City of Lino Lakes will receive wasteload allocations (WLA) for one or more of the TMDLs listed <br />above. When the WLAs are approved by the EPA, the City will need to demonstrate progress towards <br />meeting the WLAs. The MPCA is in the process of reissuing the General Permit for Small MS4s, which <br />will identify the process for demonstrating progress towards meeting a WLA. <br />Approximate City of Lino Lakes Boundary
