State officials are warning about elevated mercury levels in a species of fish at a Williams-area lake.
The Arizona Department of Environmental Quality says recent tests of black crappie from Santa Fe Lake south of Williams warrant public notification.
The department warns those who plan to eat black crappie from Santa Fe Lake to limit their servings to two-and-a-half ounces per week for adults, and two ounces a week for those under the age of 12.
A release from ADEQ says other varieties of fish found in the lake have not been found to have elevated mercury levels, and the lake remains safe for swimming, bird watching and other recreational activities.
