Seven Oklahoma lakes have been added to the Oklahoma Department of Environmental Quality list of lakes with consumption advisories for mercury.
Five other lakes were removed from the list since recommendations were last made early in 2020.
The lakes with new advisories are:
- Chandler Lake
- Lake Hefner
- Shawnee Twin Lakes
- Sooner Lake
- Lake Tenkiller
- Lake Texoma
- Lake Thunderbird
Each of the above listed lakes has recommendations specific to that lake. The levels of mercury in a lake do not affect the lake’s safety as a source of drinking water or for lake recreation such as swimming and boating according to the DEQ.
The consumption advisories are the result of testing done by DEQ with the cooperation of the Oklahoma Department of Wildlife Conservation (ODWC). Many of Oklahoma’s lakes have been tested to determine mercury levels. Currently, 66 lakes in the state have specific advisories for mercury.
DEQ recognizes the importance of the sport of fishing in Oklahoma. Fish provide many benefits that are essential for a healthy diet. Some fish do pose a higher risk for mercury contamination; therefore, DEQ encourages people to be mindful of the type and amount of fish they eat.
