  • NR 13-043: Walleye in Center Hill Lake threatened by low dissolved oxygen levels

    LANCASTER, Tenn. (Oct. 11, 2013) – Over the past few weeks several dead walleye have been observed at Center Hill Lake. Walleye prefer a cool-water habitat, which means they are usually located fairly deep in the lake this time of year. This year the dissolved oxygen levels in this zone are very low. Data collected yesterday indicated that the only area deeper than about 35 feet that contains any oxygen is a zone between depths of 60-to-90 feet, and even there the levels are quite low.
