||The Arkansas 1998 Section 303(d) List included stream reaches that were impaired due to excessive concentrations of mercury in fish. This TMDL study addresses 5 of the listed stream reaches. In addition, 8 lakes in Arkansas and 1 additional river reach are under fish consumption advisories as a result of high mercury concentrations in fish. These waterbodies are also addressed in this TMDL study. While there have been no known violations of the numeric mercury water quality standard and fishable designated use for these waterbodies, they are not meeting the narrative water quality standard and designated uses of fishable waterbodies. The waterbodies included in this TMDL study are located predominantly in central and northern Arkansas, although there are a couple in the southwest corner of the state. Waterbodies that were close together and had similar watershed characteristics were grouped together because of similar causative factors such as atmospheric and geologic contributions. As a result, TMDLs were completed for 5 watersheds that included the waterbodies of interest for this study.
