The Zhelin Reservoir (Chinese: 柘林湖; pinyin: Zhèlín Hú, Gan: Chā-līm fîkhú),[1] also named Mount Lu West Sea (Chinese: 庐山西海), is a reservoir located in the counties of Yongxiu, Wuning, and Xiushui in Jiujiang, China.

The reservoir is the largest in Jiangxi province, with a storage capacity of 7,920,000,000 cubic metres.

[2] Although the dam is located in an area of low seismic activity, after the impounding of the Zhelin Reservoir, seismic activity increased markedly.

[4] It has an average water depth of 45 meters and a visibility of more than 9 meters, rich in wild fish species, like Culter alburnus, Red-tailed Xenocypris, Xenocypris davidi, and Siniperca chuatsi.

Survivor host Jeff Probst claimed that this was the first American television series to be filmed entirely within China.
