On November 10, 2016, ADEQ announced the EPA completed its review of the Arkansas Regulation 2, which establishes water quality standards for surface waters throughout the state of Arkansas. As part of the review process, EPA approved most of the proposed revisions to the regulation including adopting site specific criteria on Beaver Lake. The provision found in section 2.509, Nutrients, states the site-specific criteria to be:
- Growing season geometric mean of chlorophyll a concentration: 8 µg/L
- Annual Average of Secchi transparency: 1.1 meters
for measurement at Hickory Creek site over the thalweg, below the confluence of War Eagle Creek and the White River in Beaver Lake.
