This agreement provides funding to the state of oklahoma to carry out its program to maintain, protect, and improve the water quality of its rivers, lakes, streams, groundwater, and other waterbodies

The Oklahoma Secretary of Energy and Environment received a $249,275 Formula Grant award effective October 1, 2025, through EPA Region 6 under the Water Pollution Control State, Interstate, and Tribal Program Support program (CFDA 66.419). This award supports the state's comprehensive water quality monitoring and assessment activities through December 31, 2026. The primary deliverable is a statewide probabilistic monitoring program encompassing 30-35 sampling stations annually across three aggregated ecoregions: the Western Plains-Tablelands, Forested Plains-Flint Hills, and the Temperate Forests-Arkansas Valley. The Oklahoma Water Resources Board (OWRB), the primary subrecipient, will conduct stream and river sampling, process and analyze water quality data, and submit findings to the state's Integrated Report and the EPA's Water Quality Exchange (WQX) database to support surface water quality characterization and impaired waterbody identification.

In addition to stream and river monitoring, the Oklahoma Conservation Commission will conduct wetlands sampling at ten sites statewide to support the EPA's National Wetlands Condition Assessment. The program's environmental benefits include preventing degradation of unimpaired waterbodies and reducing the number of impaired waterbodies across Oklahoma. Key deliverables include the Statewide Probabilistic Monitoring Final Report, contributions to Oklahoma's Integrated Report, and water quality data submissions to the EPA's WQX database, all designed to support the state's Clean Water Act compliance and surface water protection objectives.

The environmental benefits of this program include preventing degradation of unimpaired waterbodies and reducing the number of impaired waterbodies in the state. Activities:activities include continuing the probabilistic survey approach for streams and rivers including approximately 30 - 35 stations annually characterizing three aggregated ecoregions: the western plains-tablelands, forested plains-flint hills, and the temperate forests-arkansas valley. The state will process and analyze data from streams and rivers for inclusion in the statewide probabilistic monitoring final report and oklahoma's integrated report. The state also will upload the sampling data into EPA's water quality exchange (WQX) database. In addition, the state will participate in EPA's national wetlands condition assessment by sampling at ten wetlands sites throughout oklahoma. Subrecipient:the oklahoma water resources board (owrb) will continue its statewide probabilistic survey of streams and rivers, including 30 - 35 sampling stations characterizing three aggregated ecoregions: the westerns plains-tablelands, forested plains-flint hills, and the temperate forests-arkansas valley. The owrb will process and analyze data from streams and rivers for inclusion in the statewide probabilistic monitoring final report and oklahoma's integrated report, and will upload water quality data into EPA's water quality exchange (WQX) database. In addition, the oklahoma conservation commission (OCC) will conduct wetlands sampling at ten sites in support of EPA's national wetlands condition assessment.outcomes:the anticipated deliverables include the statewide probabilistic monitoring final report, input into the state's integrated report, and submittal of water quality data into EPA's water quality exchange (WQX) database. The state also will submit sampling data to WQX from ten wetlands sites as part of EPA's national wetlands condition assessment. The expected outcomes include an improved understanding of the water quality of oklahoma's rivers, streams and wetlands. The direct beneficiaries of the agreement are the residents of the state of oklahoma.
