A recently revamped irrigation system, including a two-year-old headgate capable of handling double the flow during high-water years, provides more than 6.11 cfs of surface water to irrigate 428 acres. This abundance of cold, spring-fed water supports a thriving fishery for approximately five miles along both Grass Creek and the Little Sandy Creek, all within the ranch's deeded boundaries. Anglers will find a strong population of brook trout, with brown trout also present and seasonal appearances by spring rainbow and cutthroat trout.Land & OperationsThe ranch is a functional and efficient agricultural operation, historically running 450 pair from June 15th to November 15th, with a total of 1800 AUMs. The offering includes 1,000 deeded acres within the 1,770 acre Grass Creek BLM Allotment.
