More resources on water management and environmental issues related to our mission:
- CANNON RIVER WATERSHED PARTNERSHIP (CRWP) – our lake association belongs to the CRWP, which is active in working on water quality issues in our region. Among the interesting items on the organization’s web site is its 2009 annual report and its November 2009 Watershed Watcher newsletter, which discusses septic issues and Clean Water Amendment grants.
- MINNESOTA WATERS – This is the umbrella organization for all lake associations in the state. Its web site is full of great resources for people who care about lake and water quality issues. Here are the two latest newsletters:
- Rice County Soil & Water Conservation District – September 2009 newsletter
- Minnesota Pollution Control Agency. Among the useful items on the MPCA’s web site is its summer issue of Environment magazine, which has an interesting discussion on page 16 about the cost of cleaning up a lake versus preventing its degradation in the first place, and the Fall 2001 issue, which discusses how long it takes a lake to recover after the incoming phosphorus is reduced.

- Lakeshore Property Values and Water Quality – this June 2003 study, from the NRCS web site, is a study of lake water quality’s effect on lakeshore property values, completed in 2003 by Bemidji State University and the Mississippi Headwaters Board. They were able to correlate the rise and fall of property values with the increase and decrease iin Secchi depths. One lake (Leech) showed that a one meter increase in the Secchi depth, from 3m to 4m, would raise the property values by $424/frontage foot! So a 150 ft. lot price would rise $63,600! There was an even larger effect in the other direction. A one meter decrease in the Secchi depth would cause a property value drop of $594/frontage foot.
