2024 Map of Twin Forks Reservoir

About this map

Twin Forks Reservoir and Gagena Reservoir sit at the center of this Dawson County landscape, illustrating the critical role of water management in eastern Montana. The terrain is defined by the elevation of Blue Mtn and a network of drainages including Frank Creek and Magpie Creek. This modern survey details the infrastructure of the high plains, where the Labelle Ditch and Upper Labell Reservoir facilitate the movement of water across a sparsely populated agricultural and ranching interior. Located in the sections of t14n r56e and t13n r57e, the map traces the subtle contours of the badlands and coulees that feed into Glendive Creek in the northeastern corner. This topographic study is an essential resource for understanding how land use and water storage continue to shape this portion of the Montana prairie.
