2017 Rush Lake/Goose Lake TMDL Implementation Program

Goose, East and West Rush Lakes are not meeting state water quality standards due to excessive phosphorus. These are three of the worst lakes in Chisago County in terms of water quality, yet also some of the most heavily used lakes for recreation. The quality of the water in the St. Croix River is directly influenced by the poor quality water leaving East Rush, West Rush, and Goose Lakes. The goal of this project is to reduce watershed phosphorus loading to the lakes by at least 20 pounds per year by implementing 20 best management practices directly targeting high priority areas identified a significant contributing sources of phosphorus.
