Celebrating Over 35 years of Conservation
More than 50 erosion control dams were built in Colorado’s Osier Basin, thanks to support from Wildlife Forever. The small rock dams will control erosion and help keep nearby Osier Creek suitable for trout. The 12- to 18-inch tall dams are spaced every 20 to 30 feet in some gullies. Other eroded areas will be planted with native grasses. The waters are home to native Rio Grande cutthroat trout, a Colorado state sensitive species. The remote area and rugged high-altitude terrain required a four-man crew to move the rocks and build the structures once the stone was hauled to a nearby area. This serious of dams joins a nearby group of dams that were erected 50 years ago and continue to control erosion.
