• • RCWD Policy: Manage district -owned facilities in accordance with the original design purposes, periodically review these purposes, and modify operation in consideration of current resource management objectives. 4.2. Water Quality Issues City lakes Marshan, Rice, Reshaneau, Centerville, George watch and peltier are classified as impaired for swimming. Hardwood Creek and Clearwater Creek for Biota. The hardwood Creek TMDL is finalized. The watershed is processing TMDL studies for the rest of the impaired waters in the City. Current data already suggests that the City has water quality issues. Several City lakes, such as Bald Eagle, Peltier, George Watch, Marshan and Centerville, are included in the MPCA's July 8, 2002, proposed Total Maximum Daily Load (TMDL) list because of excess nutrients that makes swimming an unsupported lake use. In addition, both Clearwater and Hardwood Creeks are also included in TMDL list because of impaired biota. The RCWD Water Management Plan regards George Watch and Marshan Lakes as Type 5 wetlands due to their shallow depths, organic bottom material and emergent vegetation. As a result the City views these lakes as functioning properly within their wetland classification and believes they should be removed from the TMDL list. Furthermore, the City has little influence on the status of Bald Eagle Lake because the City does not have control of a significant drainage area to it. Much the same is true of Hardwood and Clearwater Creeks; in both cases the vast majority of their drainage originates upstream of the City. Total Maximum Daily Load (TMDL) studies are being coordinated with the RMP to understand the source of excess phosphorus in several of the lakes. The Peltier /Centerville TMDL study is being funded by the MPCA. The second TMDL study, being funded by the RCWD, includes the Chain of Lakes downstream of Peltier. To identify phosphorus sources and loads, subwatershed catchment areas were broken out and modeled. The TMDL studies will discuss the relevance of the loading to lake impairment. In this document, loading is discussed with respect to wetlands and the implications for wetland management. TMDL: A significant resource protection issue appears to be the spreading of manure adjacent to HWC /JD2. VLAWMO: Amelia Lake rated as high priority wetlands by VLAWMO and some rare natural features present. Goals & Policies Goal: Protect and improve water quality and the scenic and ecologic values of City lakes. Policy: Preserve and improve the recreational resources associated with water. Policy: In cooperation with RCWD and VLAWMO, establish Maximum Acceptable Nutrient Concentrations (MANC) in streams contributing runoff to recreational lakes. Policy: In cooperation with RCWD, adopt standards for storm water runoff quality from new and re- developments. City of Lino Lakes SWMP :toiler 2011 1 5
