Water Quality Division
WQ Assessment Program
The Oklahoma Conservation Commission (OCC) is responsible for assessing, and evaluating waters of Oklahoma to determine the impacts of NPS pollution. To accomplish this goal, OCC conducts the Nonpoint Source Assessment Program to determine the overall aquatic health of streams across the State. In general, OCC assesses water quality, stream habitat and stream aquatic communities to evaluate beneficial use support and to identify impacts from nonpoint source pollution. We also collect a variety of other information including land use, soil nutrients, atmospheric deposition, and other pertinent information. OCC stream assessments are related to specific education or demonstration projects and occur under EPA approved Quality Assurance Project Plans. One of our primary assessment programs is the Rotating Basin Monitoring Program.
The OCC relies on the assistance of several federal and state partners to review and supplement monitoring efforts. These partners are essential to the overall success of the state's NPS Assessment Program as they monitor the larger streams and rivers, lakes and groundwater.
The results of assessments are used in planning the focus of the Nonpoint Source Program, and are also used to draft the Nonpoint Source Assessment Report. OCC assessments follow peer and EPA approved Standard Operating Procedures. Collected data are stored on the national water quality STORET database found at www.epa.gov.
