Scenic Rivers Joint Study Committee
Home Meetings Reference Info
The Scenic Rivers Joint Study Committee is made up of six members divided equally between Oklahoma and Arkansas. Governor Mary Fallin appointed the Oklahoma members
in 2013. The goal of the Committee is to implement a joint study to determine the phosphorus level at which a significant shift in algae (both type and biomass) occurs resulting in undesirable aesthetic or water quality conditions. Working toward this goal, the Committee is tasked with three objectives:
- Review the phosphorus water quality standard for scenic rivers.
- Design a study and select and advise independent researchers to determine the critical phosphorous concentrations that lead to excessive algal growth in scenic rivers.
- Use the results of the study to further investigate whether the current phosphorous water quality standard is an appropriate number to protect scenic rivers from excessive algae growth.
Oklahoma’s current phosphorous standard for its six scenic rivers is 0.037 mg/L, but levels are often found to be in the range of 0.01 - 0.15 mg/L at the Illinois River near the Arkansas-Oklahoma border. Concentrations are even greater during storm events. Phosphorous concentrations that cause a noticeable increase in algae growth are critical to all rivers, but by law scenic rivers have extra protection to preserve their high quality and unique characteristics. Sources of phosphorous in freshwater include runoff from urban development, agricultural operations, soil and streambank erosion, and wastewater and industrial discharges.
