TMDL Implementation Plan for Martin and Typo Lakes and the W. Branch of the Sunrise River between the Lakes

Typo Lake and Martin Lake in Anoka and Isanti Counties, Minnesota (Figure 1) are on the Minnesota Pollution Control Agency's (MPCA) 303(d) list of impaired waters for excess phosphorus (P) (Table 1). Phosphorus causes algae blooms that impede swimming, fishing, and other recreation. The portion of the West Branch of the Sunrise River connecting the lakes, referred to as Typo Creek, suffers from high pH and turbidity as a result of high algal productivity in Typo Lake (Table 1). It is also on the MPCA's 303(d) list of impaired waters. From 2001 to 2009 a Total Maximum Daily Load (TMDL) study investigated the causes of these water quality problems. This report follows the TMDL report, and is an Implementation Plan of actions to achieve water quality goals.
