NAMPA, Idaho (AP) — Canyon County Commissioners in southwest Idaho say they will not use local law resources to enforce on-water regulations that might be enacted by federal authorities on Lake Lowell at the Deer Flat National Wildlife Refuge.

The Idaho Statesman reports the commissioners on Tuesday said they will not abide by federal rules until federal agencies prove the federal government has jurisdiction over the irrigation water that fills the lake. The U.S. Fish and Wildlife Service in March released a new draft plan for proposed changes at the federally managed refuge in southwest Idaho.

The agency is attempting to balance its responsibility of managing a wildlife refuge with the recreational desires of local residents. Limits on boating, such as no-wake zones, are being considered.
