Benton Lake National Wildlife Refuge is managed as part of the Western Montana National Wildlife Refuge Complex. A Complex is an administrative grouping of two or more refuges, wildlife management areas, or other refuge conservation areas that are managed from a central location. Refuges are grouped into complexes because they occur in a similar ecological region, such as a watershed or specific habitat type, and have a related purpose and management needs. 

For the Western Montana National Wildlife Refuge Complex, the project leader is stationed at Benton Lake National Wildlife Refuge and oversees general management of the Complex. Refuge managers oversee the operations at specific refuges. Supporting staff, composed of administrative, law enforcement, refuge manager, biological, fire, visitor services, and maintenance professionals support all refuges within the complex.

• Benton Lake National Wildlife Refuge
