Hardwood Creek TMDL and Implementation Plan In 2002, Hardwood Creek was listed on Minnesota's 303(d) List of Impaired Waters, for biological impairment resulting from a low fish index of biological integrity (IBI) score. In 2004, Hardwood Creek was again listed on Minnesota's 303(d) List of Impaired waters for biological impairment, this time due to low Dissolved Oxygen (DO). Due to the fact that both Total Maximum Daily Loads (TMDLs) are intrinsically linked, this TMDL study encompasses both impairments. The TMDL study entailed analysis of existing data, intensive synoptic water quality and biological surveys of the creek, completion of the stressor identification process, watershed modeling, and the development of implementation strategies to meet the goals of the TMDLs. Approximately 4% of the 16,000 acres drainage area lies within Lino Lakes Peltier Lake and Centerville Lake TMDL The Peltier Lake and Centerville Lake TMDL address nutrient impairments in Peltier Lake and Centerville Lake. The EPA approved TMDL report (September 2013) states that nutrient load reductions of about 37% are needed for Centerville Lake and reductions of 79% to 85% are needed for Peltier Lake. Lino Lakes Chain of Lakes TMDL The Lino Lakes Chain of Lakes TMDL addresses nutrient impairments in George Watch Lake, Marshan Lake, Reshanau Lake, Rice Lake and Baldwin Lake. The EPA approved TMDL report (September 2013) states that nutrient load reductions ranging from 65% to 85% are needed to meet state standards. The report further states that to achieve state water quality standards in this chain of lakes, Peltier Lake must also meet its water quality goals. Bald Eagle Lake TMDL The Bald Eagle Lake TMDL addresses nutrient impairments of Bald Eagle Lake. The TMDL report indicates that nutrient load reductions of 38% to 91% are required for the lake to meet state standards. The public comment period for the Bald Eagle Lake TMDL ended on March 30, 2011. The TMDL was approved by the Environmental Protection Agency (EPA) in June of 2012. Vadnais Lake Area WMO TMDL The Vadnais Lake Area WMO Total Maximum Daily Load (TMDL) and Protection Study addresses nutrient impairments of Wilkinson Lake among four other lakes within VLAWMO as well as the bacterial impairment of a creek in VLAWMO. The TMDL report was completed in July 2013 and provides wasteload allocations for the City of Lino Lakes with respect to Wilkinson Lake. Downstream Impairments: Middle Rice Creek Middle Rice Creek includes a stretch of river that extends from Baldwin Lake in Circle Pines to Long Lake in New Brighton. This stretch of Rice Creek is impaired for aquatic recreation and aquatic life caused by accelerated erosion and sedimentation. Middle Rice Creek flows into North Long Lake which is currently listed as impaired for excess nutrients (eutrophication). The impairment for North Long Lake was deferred by the MPCA due to extremely short water residence times in the lake, but a TMDL study for Middle Rice Creek will be completed as part of a future Watershed Restoration and Protection Plan. Lino Lakes will likely be listed as a regulated MS4 when this TMDL is developed. The Rice Creek Watershed District was recently awarded a BWSR Clean Water Fund grant. The grant is a targeted watershed demonstration grant with the ultimate goal of improving water quality in Long Lake. Grant funds will be used to stabilize the banks of Middle Rice Creek to reduce sediment and nutrient transport to Long Lake and for carp management and control for Long Lake.
