Bighorn River System Issues Group
 |
| (Above) Yellowtail Dam and Bighorn Canyon National Recreation Area. |
Purpose Statement
The Bighorn River System Issues Group is formed to identify, explore, and recommend alternative courses of action to local, tribal, state, and federal entities responsible for managing the Bighorn River system resources for their consideration as part of a long-term management strategy. The challenge is to re-examine the uses and needs of the Bighorn River system to find an appropriate balance of public benefits, while recognizing the respective agencies’ commitments to authorized project purposes, legal obligations, contemporary needs and public expectations.
Problem Statement
Local, state, tribal, and federal entities are concerned that the Bighorn River system is not being managed in a way that fully protects and utilizes the system’s resources to address the multiple demands, needs, and expectations of the public.
