Lake Thunderbird TMDL Compliance and Monitoring Plan

On Tuesday, October 27, 2015, the Norman City Council endorsed the City of Norman’s Lake Thunderbird Total Maximum Daily Load (TMDL) Compliance and Monitoring Plan, and directed city staff to submit the Plan to the Oklahoma Department of Environmental Quality (ODEQ) by the prescribed deadline of November 10, 2015. When approved by ODEQ, but no later than January 11, 2016, implementation of the Plan by the City of Norman will begin.

In November 2013, the Oklahoma Department of Environmental Quality (ODEQ) finalized a TMDL study and report for Lake Thunderbird that determined the reduction of pollutants (total suspended solids, chlorophyll-a, nitrogen and phosphorus) required in the lake to meet water quality standards. The study results concluded that compliance and monitoring plans should be developed to determine best management practices designed to reduce pollutants in the next 20 years and show sustained progress toward reduction in daily amounts of total pollutants entering Lake Thunderbird.
