Water Quality Testing - RMB Labs
RMB Environmental Labs, Inc. performs the testing of our samples. Samples are taken from three sites on the lake five times during the open water season. The sites are designated as main lake (203), west bay (206) and south end(207). Collections are taken on Sunday afternoons for delivery to the pick up site on Monday morning.
RMB's website has all the information on the results of the testing from a one page summary to indepth details depending upon what you want to look at.
Below is a one page summary of the 2007 to 2012 time frame and a info on long term trends.
