This legislation aims to secure water rights and enhance land resources for the Fort Belknap Indian Community in Montana, which includes the Gros Ventre and Assiniboine Tribes. By ratifying a water rights compact established in 2001, the bill seeks to resolve longstanding water rights claims, ensuring the community has reliable access to essential water resources for agricultural and domestic use. The bill facilitates the transfer of approximately 3,519.3 acres of federal land and 20,000 acre-feet of water annually from Lake Elwell to the Fort Belknap Indian Community.
