Department of Natural Resources

Public Notice

The Department of Natural Resources has moved from 100 West Main, Suite 304, to 102 Midland, Pawhuska, OK 74056.


Our mission is to protect human health, the environment and our cultural resources, and to protect and develop our natural resources while preserving the diverse human cultures and unique ecosystems that exist within the Osage Nation.


The Department of Natural Resources (DNR) coordinates the EPA Underground Injection Control (UIC) grant, EPA Clean Water Act 106 grant, EPA General Assistance Program (GAP) grant, and the U.S. Geological Survey (USGS) hydrogeology project. In addition to these grant projects, DNR continually seeks to build capacity through the development of projects that benefit the Osage Nation, through conscientious land/natural resource management, threatened and endangered species programs, and environmental review preparation. These programs work to protect and enhance the natural resources and environment within the Osage Nation, while keeping the Osage Nation in compliance with all applicable federal laws.

EPA UIC Grant - This grant is funded through the U.S. Environmental Protection Agency (EPA). Through this program, the Osage Nation conducts inspections of all Class II injection wells, witnesses plugging of Class II injection wells, tests injection wells for mechanical integrity, and assists EPA with compliance and enforcement on wells.

EPA Clean Water Act 106 Grant – This grant is funded through the U.S. Environmental Protection Agency (EPA). Through this program, the Osage Nation monitors surface water to assess water quality within specific drainage basins and watersheds. All surface water samples are collected and analyzed in the Osage Nation water laboratory. Under this program, fish collections and macroinvertebrate collections are completed to evaluate the condition of each water body using biological measurements of the resident biota in the water.

EPA General Assistance Program – This grant is funded through the U.S. Environmental Protection Agency (EPA). Through this program, the Osage Nation performs a systematic reconnaissance of tank batteries and catalogues locations around tank batteries, well heads, and injection wells where saltwater spills have occurred. Road side or private dumpsites are also located and identified.

USGS Hydrogeology Project – This project is to implement the "Investigation of Hydrogeology and Water Availability in the Osage Nation of Oklahoma". Under this project, the Osage Nation has coordinated with USGS to house subsurface geology maps for Osage County. Within these maps include information on water availability based upon the subsurface geology examination.


The following Osage Nation Water Regulations are the promulgated and final rule of the Osage Nation Department of Natural Resources (“DNR”). These regulations allow the DNR to take a positive role in managing and conserving the natural resources that are important to the Nation and the Osage people. The Osage Nation Water Regulations establish a system for drilling and monitoring water wells on Osage land. This system fills a current void and allows for the monitoring of groundwater use for future sustainability and conservation.


By the authority vested in the Department of Natural Resources (“DNR”) pursuant to ONCA 17-35 and in order to carry out its duties and responsibilities under the Osage Nation Wildlife Conservation Act, the DNR promulgates and publishes the following Wildlife Conservation Regulations. These Regulations shall serve as the interim final regulations in order to protect and preserve all wildlife within the Osage Nation Reservation and prevent any damage to the interest of the Osage Nation during the upcoming hunting season.


It is the policy of the Osage Nation Executive Branch that all complaints filed by constituents of the Osage Nation receive prompt and careful attention, and receive a timely response. Some complaints may be referred directly to the Osage Nation Attorney General while others will be investigated by the Executive Branch. In either case, constituents will be notified of the status of their complaint within thirty (30) business days of receipt.

For your convenience, we provide an electronic form to submit your complaint. You may still submit your complaints in person, or via the telephone. For more details on this, please read the Complaint Policy.
