Cedar Island, Pike, and Eagle Lakes Nutrient TMDL Final

This Total Maximum Daily Load (TMDL) study addresses nutrient impairments in the Eagle Lake chain of lakes. The goal of this TMDL is to quantify the pollutant reductions needed to meet State water quality standards for nutrients in Cedar Island (27-0119-00), Pike (27-0111-02), and Eagle (27-0111-01) Lakes. Water quality in Cedar Island and Pike Lakes is considered poor with frequent algal blooms while Eagle Lake has more moderately degraded water quality. Both Cedar Island Lake and Pike Lake drain into Eagle Lake and likely have a large influence on water quality in Eagle Lake. The most severe algal blooms in Eagle Lake occur in late summer. Cedar Island Lake is shallow and has extremely high total phosphorus concentrations and extremely severe algal blooms. Cedar Island Lake has a large internal load that is exacerbated by the presence of curly-leaf pondweed in nuisance densities. Pike Lake is also shallow and has high total phosphorus concentrations throughout the summer with severe algal blooms
