LAKE WATER QUALITY MONITORING PROGRAM
Lake water quality monitoring is conducted on many lakes in Washington County as a part of the Metropolitan
Council's Citizen Assisted Lake Monitoring Program (CAMP). WCD staff monitors the water clarity, dissolved oxygen, temperature,
and nutrients on a monthly or bi-monthly basis in each.
The data gathered is provided to the Minnesota Pollution Control Agency (MPCA) to determine if water resources
are not meeting water quality standards and criteria. If these resources are not meeting these standards and criteria, they are
classified as "impaired." Once an impairment is determined, a study known as a TMDL or Total Maximum Daily Load must be performed
to determine the stressor or pollutant causing the impairment. Once the problem is identified, a plan is developed to determine
how much less of the stressor(s) or pollutant(s) need to prevented from reaching the water resource to meet water quality
standards and criteria.
