The North Branch of the Sunrise River was placed on Minnesota’s impaired waters list in 1998 due to excessive levels of fecal coliform bacteria. The river, from its headwaters in Isanti County to its confluence with the Sunrise River in Chisago County, is impaired for swimming and other primary contact recreation. The Chisago County Water Plan Policy Team was involved in the development of the TMDL project. The TMDL was approved by the EPA on February 22, 2007. The Implementation Plan was approved by the MPCA in February 2007 and implementation activities are currently underway.
