Ships gather at lock anchorage upstream of Three Gorges Dam in central China

Photo taken on March 3, 2026 shows numerous vessels anchored at the waiting lock area upstream of the Three Gorges Dam in Zigui County, Yichang City, central China's Hubei Province. Located at the head of the reservoir, Zigui County serves as a gathering point for downstream vessels and a collection area for floating debris in the Three Gorges Reservoir. Environmental protection boats handle wastewater, domestic garbage, and oily water from passing ships. When docked at the port or waiting for the lock, vessels turn off diesel generators and connect to shore power, conserving energy and protecting the environment. (Zheng Kun/Guangming Picture)
