Location

Percha Diversion Dam was completed on the Rio Grande in 1918, 21 miles south of Truth or Consequences, New Mexico. It is two miles downstream from Caballo Dam, which was built in 1938. It is listed on the National Register of Historic Places. The dam is accessible within the 80 acres (32 ha) Percha Dam State Park, which is considered one of the top five bird-watching sites in New Mexico.[2]

Structure

The dam is a reinforced concrete weir, 350 feet (110 m) long and 18.5 feet (5.6 m) tall. When the embankment wings are included the crest is 2,720 feet (830 m) long. The dam includes eight Tainter gates that lift the level of the river 6 feet (1.8 m) above its normal elevation so it can be diverted into the canal.[2]

Downstream canal

Percha Diversion Dam diverts the stored water into the 27.1 miles (43.6 km) long Rincon Valley Main Canal, which carries water to irrigate lands in the Rincon Valley between Truth or Consequences and Las Cruces, New Mexico. The Rincon canal crosses over the Rio Grande in the Garfield Flume, and under the river in the Hatch and Rincon siphons.[2]
