Water Quality 2010

Water Quality Monitoring 2010 

Thank you to those members who contributed extra funds to the Cross Lake water quality program for 2010.   

 The water quality team plans to continue with basic lake and river monitoring using the Hach electronic system, Secchi disk, plus water sampling for phosphorous, nitrate, chlorophyll a,  e-coli bacteria, and microscopic study of zooplankton and forms of algae.  Much of this data is entered into the Citizens Lake Monitoring Program, MPCA database. 

Other equipment and methods are used for the basic MPCA Stream Monitoring Program and data is entered into the MPCA database. In addition we do testing for nutrients such as phosphorous, as well as E-coli. 

When possible we have sought grants to assist with expenses such as e-coli test supplies and for cost of shipping and testing of samples at a certified lab.   

All of this information is summarized by our team and is used by the Snake River Watershed Management Board (SRWMB), Pine County SWCD, and the Minnesota Pollution Control Agency. 

Of special importance is the implementation of a joint agency TMDL study of the Snake River Watershed in 2010.  Plans have been underway for months and our water quality team will be involved in additional monitoring this summer as part of the overall data gathering process.  We have been contributing ideas and expect to be involved as the process evolves. 

A TMDL study refers to Total Maximum Daily Load—a technical concept that refers to the maximum amount of something, such as phosphorous or bacteria that could enter the water on a daily basis without exceeding the MPCA limit.  On-going problems at a site, a stream, or a lake would lead to specific recommendations for improvement.

Come to the May Cross Lake Association meeting to hear about the the MPCA’s details of the TMDL study and its importance to water quality.
