About the Program

Monitoring Section staff direct Oklahoma's Beneficial Use Monitoring Program. BUMP, created in 1998, is the state's first truly comprehensive water quality monitoring effort. Data provided by the program plays an essential role in the state's water quality management decision-making process by helping to identify waters experiencing impairments as well as the cause of declining water quality. The BUMP is also invaluable to the development and refinement of Oklahoma's Water Quality Standards. Beneficial uses, the backbone of the Water Quality Standards, are assigned to individual lakes, streams, and stream segments based upon the primary benefits derived from those waters by the public. Each year, staff publish a report that discloses detailed physical, chemical, and biological information from 155 lakes and streams collected at approximately 600 sites throughout Oklahoma. A groundwater component was added to the BUMP in 2012 with the creation of the Groundwater Monitoring and Assessment Program (GMAP). The GMAP monitoring network is comprised of approximately 750 wells in Oklahoma's 21 major aquifers (phased in by 2017 and sampled on a four-year rotation).

The OWRB conducts statistical survey monitoring throughout the state at sites selected randomly by computer. Lake and stream sites are sampled across the state. Any lakes greater than 50 surface acres in size and any stream segment can be selected for testing. A physical habitat assessment is conducted, chemistry is analyzed, and samples of algae and bacteria are collected at each waterbody. Fish and macroinvertebrate collections are also made at each selected stream site.

Since 2001, the OWRB has been conducting groundwater monitoring for the Oklahoma Department of Agriculture, Food and Forestry (ODAFF) as part of its oversight of Licensed Managed Feeding Operations (LMFOs). OWRB staff collect groundwater samples from select LMFO monitoring wells and submit them to the ODAFF’s laboratory for analysis of potential contamination of groundwater, signaled through high nitrate-nitrogen concentrations, high ammonium-nitrogen concentrations, or sample analyses containing three or more fecal coliform colonies. Quarterly and annual reports of findings are submitted by OWRB staff.
