Oklahoma Comprehensive Water Plan

Water Quality Monitoring

The OWRB's Water Quality Monitoring staff sample lakes, streams and groundwater wells throughout the year and across the state to provide data that can be used to describe both current conditions and historcal trends. Five types of sampling occur within the program: lakes, streams, biological streams, groundwater, and ambient trend. The OWRB also has probabilistic sample sites throughout the state's streams that are selected at random by computer.

Numerous and varied efforts over the past few decades have generated multiple datasets and reports:

OWRB monitoring activities provide necessary data for the following purposes:

  • Developing, refining, or modifying numerical criteria listed in Oklahoma’s Water Quality Standards;
  • Studies of Total Maximum Daily Loading (TMDL), including both stream gauge and water quality data, much of which is related to confirming 303(d) listings and determining allocations;
  • Stream gauging for numerous grants and contracts and providing discharge measurements on BUMP stations not currently gauged by the United States Geological Survey;
  • Tracking movement of pollutants from Confined Animal Feeding Operations (CAFO) in approximately 850 wells to support regulation by the Oklahoma Department of Agriculture, Food and Forestry;
  • Monitoring stream water for the Federal Energy Regulatory Commission (FERC) permitting process for hydroelectric power generation activities;
  • Collection of water and biological samples for the Oklahoma Department of Agriculture to find a continued presence or document the absence of pesticides in streams which have previously been listed on the state’s 303(d) list as being impaired for pesticides.

Groundwater Monitoring & Assessment Program (GMAP)

Representing Oklahoma’s first holistic groundwater network monitoring effort, GMAP staff are collecting baseline groundwater level and quality data from wells in Oklahoma’s twenty-one major aquifers.
