The dam is located in Changyang Tujia Autonomous County (which is part of the prefecture-level city of Yichang), just a few kilometers to the west (upstream) from the county seat, Longzhouping Town (龙舟坪镇).

The dam was designed in 1987,^[4] and is equipped with a ship lift capable of lifting vessels of 300,000 kg (660,000 lb) displacement.^[5] The dam played an important role in helping to ameliorate the impact of the 1998 Yangtze Floods.

Power is generated by four units rated at 310 MW each, totalling the installed capacity at 1,240 MW.^[6]
