Costs and Responsibilities

When a lake association joins, a volunteer(s) from the group is trained to collect water samples and Secchi Disk readings. Included on-site training is available for groups of 10 or more lakes. A sampling schedule is determined per client. Typically, once a month (5 events/summer) the volunteer is sent sampling and shipping supplies. Following collection, the water samples are shipped to our laboratory for Total Phosphorus and Chlorophyll-a analysis. Our staff then enters the data into our Lakes Monitoring Database where it is available online to the public for viewing and assessment.
