[5] Baiheliang (literally meaning the "White Crane Ridge") is an archeological site in northern Fuling District that has since been submerged underwater due to the building of the Three Gorges Dam.
The stone fish figures and inscriptions recording water-levels and other information from the Tang dynasty (618–907 AD) onwards could be viewed by visitors.
From 1994, China's government departments involved with the protection of Chinese cultural heritage undertook research on the conservation of the stone inscriptions at Baiheliang.
The stone ridge has now been enclosed in an arch-shaped glass covering that is filled with purified water to ensure that pressure on both sides of the arch is the same.
Two underwater channels with long escalators have been installed from the riverbank, allowing museum visitors to descend and view the stone carvings and inscriptions.
