The Oklahoma Department of Environmental Quality (DEQ) has updated its list of lakes
with consumption advisories for mercury.  Eight Oklahoma lakes have been added
since the last advisory was issued in 2013. Those lakes are:

  • Arbuckle Lake
  • Cushing Lake
  • Meeker Lake
  • Prague Lake
  • Sportsman Lake
  • Stroud Lake
  • Wetumka Lake
  • Wewoka Lake

Each of the above listed lakes has recommendations specific to that lake. 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.  These eight additional lakes bring the state total to 40 lakes that have specific advisories for mercury. The following lakes had existing consumption advisories: Atoka, Boomer, Broken Bow Reservoir, Canton, Carlton, Cedar, Clayton, Coalgate City Lake, Draper, Dripping Springs, Elmer Thomas, Fort Supply, Hugo, Kaw, Carl Albert, Carl Blackwell, Eufaula, Heyburn, Nanih Waiya, Ozzie Cobb, Talwanda No. 2, Wayne Wallace, Church Lake, McAlester City Lake, McGee Creek, Pine Creek, Quanah Parker, Rush, Sardis, Schooler, Skiatook and Wister.

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 amount of fish they eat.

DEQ actively promotes fishing and urges Oklahomans to enjoy the sport while following the  suggested guidelines for fish consumption. 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.
