Water Regulations:

The following Osage Nation Water Regulations are the promulgated and final rule of the Osage Nation Department of Natural Resources (โ€œDNRโ€). 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.
