Monitoring & Assessment

Lakes Monitoring

Lakes monitoring data collected by the OWRB are important indicators for determining compliance with water quality standards, tracking general water quality trends, and identifying pollution problems. Monitoring staff also conduct lake restoration activities and bathymetric mapping to determine lake storage capacity.


Beneficial Use Monitoring Program

Through the Beneficial Use Monitoring Program (BUMP) the OWRB collects data at approximately 130 lakes on a quarterly basis utilizing a five-year rotation schedule. Data collections include a broad-base of chemical, physical, and biological parameters. Data collected from these sites allows for long-term assessment of beneficial uses and water quality trends. ...more

Lake Restoration

Improving the water quality of Oklahoma’s lakes is vital to quality of life for Oklahomans. OWRB staff are engaged in providing information and recommendations to improve lake water quality conditions. Projects may be focused on issues such as sediment removal, oxygenation, shoreline revegetation, and erosion control. Final reports of past projects are available under Lake Resoration on the OWRB's Technical Reports web page.


Bathymetric Mapping

The OWRB's bathymetric mapping program utilizes GIS and related technology to provide accurate determinations of current storage capacities in the state's reservoirs. Contour maps are then derived from collected data points and digital lake bottom surface models.

Lake Arcadia Pre-TMDL Study

In cooperation with the Oklahoma Department of Environmental Quality (ODEQ), the OWRB is conducting a pre-TMDL study on Lake Arcadia, a 1,676-acre, hyper-eutrophic, urban lake in Edmond, Oklahoma. Water quality data is being collected to verify waterbody impairment to support TMDL development for the lake. ...more


Lake Thunderbird Monitoring and Analysis

The OWRB has worked with the Central Oklahoma Master Conservancy District (COMCD) for more than 20 years to provide water quality monitoring and analysis at Lake Thunderbird, creating a long term dataset to assist the COMCD in making lake management decisions. ...more
