Outlet Channel

Maintaining an unimpeded flow from Big Marine Lake through Little Carnelian Lake and the outlet pipe to the St. Croix River is a critical responsibility of the Watershed District.  CMSCWD was formed to reduce the threat of flooding in Big Marine and Carnelian Lakes and the solution was the result of many years of study of the causes to these water fluctuations.  Some of the reports that examine the causes of these water fluctuations are:

The range of elevations that the District maintains is a result of negotiations with riparian property owners and the Department of Natural Resources to both protect property and protect wetlands within the watershed.  The only variable in the system is an adjustable weir downstream of the fixed outlet and Turtle Lake.  The current management plan for the weir has evolved over the years and was approved by the DNR in 2004. The management plans are available for review here, from the current plan to the original management plan:
