Typo Lake and Martin Lake TMDL

Typo Lake and Martin Lake in Anoka and Isanti Counties, Minnesota (Figure 1) are on the Minnesota Pollution Control Agency's 303(d) list of impaired waters for excess nutrients (Phosphorus). The lakes are linked, with Typo Lake flowing to Martin Lake via the West Branch of the Sunrise River (HUC# 07030005-563), aka Typo Creek. This reach of Typo Creek was added to the 303(d) list of impaired waters in 2006 for pH and excess turbidity. These lakes and the stream linking them were studied together because their problems are related. This report details the current conditions, sources of phosphorus (P), water quality targets, and prioritizes phosphorus reduction opportunities.
