The dam sits a few kilometers upstream from downtown Yichang, just downstream of the fall of the Huangbo River into the Yangtze. Construction started on December 30, 1970 and ended on December 10, 1988. The dam has a total installed electrical capacity of {{nowrap|2,715 MW}}.[1] After rushing out of Nanjin Pass (南津关, "South Ford Pass"), the Yangtze River slows down and widens from {{convert|300|m}} to about {{convert|2200|m}} at the dam site. Two small islands, Gezhouba and Xiba, divided the river into three channels. There the Gezhouba Project was built. The facility boasts a generating capacity of {{nowrap|2.71 GW}} along with three ship locks, two power stations that generate {{nowrap|14,100 GWh}} of electricity annually, the 27 gates of the spillway, and the no flowing Dam on both banks. The dam is {{convert|2595|m}} long with a maximum height of {{convert|47|m}}. The reservoir has a total volume of {{convert|1.58|km3|acre.ft}}. The navigation lock {{nowrap|No.2}} on the third channel was, when built, among the 100 largest in the world. The lock chamber is {{convert|280|m}} long and {{convert|34|m}} wide, with a minimum draft of {{convert|5|m}} at the sill. It provides passage for 10,000 ton ships. The construction of the Gezhouba Dam, and others on the Yangtze, is considered by scientists to be one of the main causes of the decline and probable extinction of the Chinese paddlefish.[2] See also{{stack|{{Portal|China|Water|Renewable energy}}}}
