The Tyrone Dam
The Tyrone Dam and Pond were built in 1846 to provide power for a grist mill, sawmill and apple cider production. The structure is impassable to lake-run fishes. Chinook and coho salmon and rainbow trout have all been documented up to but not upstream of the structure for many years. The Tyrone Dam isolates a native Brook Trout population from competition with stocked Brown Trout.
