SOUTH FORK, Colo. - Fire managers say the West Fork Fire complex is now 25 percent contained but the fire has burned a small pump house east of the Rio Grande Reservoir.
Officials said Friday that no other structures have been damaged.
The complex, which contains three fires, has grown to more than 170 square miles.
The complex involves the West Fork, Windy Pass, and Papoose fires. They are burning on the San Juan and Rio Grande National Forests and private lands in southern Colorado.
The fires are burning between the cities of Creede, South Fork and Pagosa Springs in areas of rugged terrain and beetle-killed spruce. Because of those conditions, firefighters have had a difficult time mounting direct attacks on the fire perimeters.
