Water Quality

Healthy Lakes – Water Quality

We continue to have water samples chemically evaluated for total phosphorus and chlorophyll by the RMB Environmental Laboratories, Inc in Detroit Lakes.

Five samples. Approximately one per month from May to September, will be taken from Child Lake, Woman Lake, Broadwater Bay and Girl Lake. Secchi Disc readings are simultaneously taken by our volunteers. Thanks to Arlan Schires, Bob Hankey, Keith Lorensen and Gary Meyer. The date is entered by the Laboratory into the Environmental Protection Agency’s (EPA) database stored nationwide and is also available on the RMB website, www.rmbel.info . The website includes many resources and links, including an online Limnology Primer for those wishing to understand more about water quality.

The three measurements taken are related. When phosphorus increases there is more food available for plants and algae. Then algae increases and the water become  less transparent and so the secchi depths decrease. In order to develop a more in-depth picture of our lakes water quality measurements need to be taken over many years. For the years 2008-2015 we will have 40 measurements for each of our four sampling sites. We hope to continue this program.

The water level of our lakes has been about as high as history records due to much rainfall in June and July. As a result much runoff and shore erosion has occurred affecting the water quality. Look for the Property Owners Tree Sampling Program of our Association to help improve the shoreline beauty and lakeshore structure of our lakes. A rise and fall of some six inches of water depth over some 6000 acres is a lot of gallons!
A Pocket Guide to Reducing Your Water Footprint is available from the Water Resources Center at the University of Minnesota by downloading it from their website, www.wrc.umn.edu

The water footprint is the total volume of freshwater used to produce the goods and services consumed by that person every day. By saving water and by reducing the amount of contaminates you add to it, you’re supporting healthy lakes and streams and preserving Minnesota’s most vital natural resource. For example, a typical Thanksgiving dinner for six requires more than 30,000 gallons of water. Many surprising bits of water use data are available upon reading the guide, and may affect our habits in the kitchen, laundry, bathroom, yard and garden.
