An impoundment on the Caney Fork River, Center Hill Reservoir is north of Smithville and south of Interstate 40 in Middle Tennessee.

The advisory applies to walleye 19 inches and larger for the entirety of the reservoir based on data exceeding Tennessee’s trigger point for mercury. Mercury in walleye 19 inches and larger averaged 0.39 mg/kg, which is above the trigger point of 0.3 mg/kg. The advisory is consistent with TDEC’s responsibilities under the Tennessee Water Quality Control Act.

“Unlike ‘Do Not Consume’ advisories that warn the general population to avoid eating fish from a particular body of water altogether, precautionary fish consumption advisories are specifically directed to sensitive populations. They include children, pregnant women, nursing mothers, and those who may eat fish frequently from the same body of water,” said Ronné Adkins, deputy commissioner for Environment at TDEC. “These advisories help the community make informed decisions about whether or not to consume the fish.”

TDEC will post warning signs at primary public access points and will work with the Tennessee Wildlife Resources Agency to communicate this information to the public.

About Fish Consumption Advisories

The Tennessee Water Quality Control Act identifies the commissioner of the Tennessee Department of Environment and Conservation as having the authority and responsibility to issue advisories for either water contact hazards like pathogens or excessive health risks due to the accumulation of contaminants in fish or shellfish. Tennessee’s General Water Quality Criteria provide additional guidance regarding the conditions under which advisories may be warranted.
