The Bureau of Land Management announced Thursday it reached agreement with Alaska about the ownership of submerged lands beneath four river basins in the state.

The agency issued formal notifications confirming that Alaska owns the lands across several waterways: the Delta-Tangle River System and Tangle Lakes System, West Fork Dennison Fork and Dennison Fork of the Fortymile River System, Kwethluk River, and Goodnews River System.

The rulings, the first since 2019, add to more than three dozen similar notices BLM has issued since 2003, according to a Government Accountability Office.

“Today’s decisions show what can be accomplished when the Bureau of Land Management and the State of Alaska work together to provide the clarity, certainty, and results Alaskans deserve,” said Kevin Pendergast, BLM Alaska state director. “These historic decisions reduce uncertainty, improve public understanding of ownership, and help ensure Alaskans know which authorities apply on these submerged lands.”
