Английская Википедия:Heron Dam
Шаблон:Infobox dam 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.Шаблон:Sfn The dam is about 9 miles west of the town of Tierra Amarilla.Шаблон:Sfn
Construction
The dam was built as part of the San Juan–Chama Project, which transfers water from the San Juan River basin through the Шаблон:Convert 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.Шаблон:Sfn Construction was completed in 1971.Шаблон:Sfn 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 Шаблон:Convert per second.Шаблон:Sfn
Structure
The reservoir lies at an elevation of Шаблон:Convert above sea level. The earthfill dam is Шаблон:Convert long and Шаблон:Convert high.Шаблон:Sfn Heron Dike, one mile northwest of the dam, helps contain the reservoir. It has a concrete crest spillway with an open chute with a discharge capacity of Шаблон:Convert per second. The dam's outlet works include an intake structure, Шаблон:Convert diameter concrete-lined upstream tunnel, gate chamber, Шаблон:Convert modified horseshoe concrete-lined downstream tunnel, and a stilling basin. The discharge capacity is Шаблон:Convert per second at a reservoir elevation of Шаблон:Convert.Шаблон:Sfn
When filled, the reservoir covers Шаблон:Convert.Шаблон:Sfn The maximum safe storage capacity is Шаблон:Convert. Downstream channel capacity is about Шаблон:Convert per second.Шаблон:Sfn
Operations
The dam was built strictly for storage and delivery of San Juan-Chama Project water for municipal, domestic, industrial, recreation, irrigation, and fish and wildlife purposes. The water is diverted to New Mexico as agreed under the Colorado River and Upper Colorado River Compacts. The amount of water diverted each year, and the way in which it is used, are subject to well-defined agreements.Шаблон:Sfn Flows of "native" or "natural" water from Willow Creek and from the Rio Chama upstream of the dam are measured and bypassed through the reservoir.Шаблон:Sfn
The dam provides up to Шаблон:Convert of San Juan-Chama water annually to maintain the recreation pool at Cochiti Reservoir. The dam can supply about Шаблон:Convert of San Juan-Chama water annually to users with reasonable certainty.Шаблон:Sfn There is no carry-over provision: contractors must take delivery of their water by December 31. This means that contractors such as the City of Albuquerque or the Middle Rio Grande Conservancy District often withdraw their water and arrange to store it in downstream reservoirs such as El Vado, Abiquiu, Jemez Canyon (by exchange), and Elephant Butte.Шаблон:Sfn
