The west 793± acres of Big Spring Legacy Ranch, 10 miles northwest of Lewistown, Montana, held by the same family for more than 80 years. The property holds 1.4 miles of Big Spring Creek with ownership of both banks, and its upstream boundary sits 1.6 miles from the nearest public bridge. A 2022 Montana FWP survey on this stretch documented a self sustaining wild trout fishery, with browns outnumbering rainbows nearly 4 to 1 and browns up to 19 inches. About 158 acres are cropland, currently 150 acres of millet and 8 acres of sainfoin. Three irrigation rights cover 174± acres with priority dates back to July 16, 1893, plus six stock rights. The balance is cross fenced native range, brushy coulees and scattered timber on the southwest edge of the South Moccasin Mountains. Unimproved, with paved Hanover Road access by a 250 yard easement, three phase power in the center of the property and no conservation easement. Wildlife includes elk, mule deer, whitetail and turkey, with pheasant, sharptail and Hungarian partridge. The full 2,315.5± acre ranch is also offered.
