Fish Contamination Assessment
$135000 the first year and $135000 the second year are for assessing mercury and other contaminants of fish including monitoring to track the status of impaired waters over time.
In FY19 the DNR will test another 80 lake and river sites for fish mercury contamination to collect information other agencies use to determine fish consumption advisories impairment status and long-term statewide trends. This is in addition to the approximately 70 lakes normally tested every year for mercury and other fish contaminants using Game and Fish Funds.

The DNR works with the Minnesota Pollution Control Agency and the Minnesota Department of Health to determine the level of contamination from mercury and other harmful chemicals in fish from Minnesota's lakes and rivers and to track the success of efforts to reduce mercury pollution. Clean Water Legacy funding is being used to significantly increase (more than double) the number of lakes and rivers that are assessed for mercury contamination on an annual basis. Fish are collected during DNR fishery surveys, processed for laboratory testing, and analyzed for contaminants. The data are processed by the DNR, shared with the Minnesota Pollution Control Agency and the Minnesota Department of Health, and long-term trends are summarized in the Clean Water Fund Performance Report.
Many outdoor recreationists enjoy fishing and eating the fish they catch. Unfortunately, much of the fishery is contaminated with chemicals, primarily mercury. This has resulted in the issuance of a number of fish consumption advisories. Fish contaminant data provide the basis for these advisories. They also provide some measure of the threat to other fish-consuming species, including mink, otter, and loons. In addition, the measurement of mercury levels in fish provides an important indicator of progress in attempts to decrease the release of additional mercury into the environment.
