Notes
Lower Buckatabon Lake was put on the Impaired Waters List in the 2016 cycle for phosphorus. In the 2022 cycle a review of the lake type determined this is not a Two-Story Fishery lake, but is a Shallow Lowland Drainage lake. With the change in phosphorus criteria the lake is meeting its uses. This lake is remvoed from the Impaired Waters List. Evaluation in 2024 confirmed good condition.Pollutant
