NORMAN — The state Environmental Quality Department will hold an informational meeting Thursday on water quality issues affecting Lake Thunderbird.
The meeting will be from 6:30 to 8:30 p.m. in the Lowry Room at the Norman Public Library, 225 N Webster Ave.
State officials will discuss work toward establishing “total maximum daily loads” for the lake. Total maximum daily loads is a regulatory term in the U.S. Clean Water Act, which is a calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards.
Water quality models are used to determine the magnitude of pollutants in the lake and estimate the reduction needed to achieve water quality goals.
Officials will discuss preliminary results of a study using water quality models to determine water quality standards for the lake and provide an update on efforts to establish total maximum daily load amounts.
Lake Thunderbird is a drinking supply for Norman, Midwest City and Del City.
Problems associated with Lake Thunderbird are high chlorophyll-A levels, which come from excessive growth of algae, and high turbidity.
