Heron Dam is a storage dam Rio Arriba County, in northern New Mexico in the southwestern United States, just north of the El Vado Dam. It is owned and operated by the United States Bureau of Reclamation. The dam is about 9 miles west of the town of Tierra Amarilla. ==Construction== The dam was built as part of the San Juan-Chama Project, which transfers water from the San Juan River basin through the Azotea Tunnel under the Continental Divide into Willow Creek, where it is stored in Heron Reservoir as part of the Colorado River Storage Project. The dam is located on Willow Creek near the creek's confluence with the Rio Chama. Construction was completed in 1971. The outlet works at El Vado Dam, just downstream from Heron Dam, were enlarged as part of the San Juan-Chama Project so releases from Heron Reservoir could pass unimpeded through the dam. The capacity of the El Vado outlet works was increased to pass per second. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heron Dam」の詳細全文を読む スポンサード リンク
