This document presents comparative photographs of the Upper Dordi 'A' Hydroelectric Project structures before and after a flood. The photographs show damage to the headworks, desander, intake gate area, access roads, and other structures. Specifically, they depict debris deposits, damaged walls, and the flood entering and damaging areas like the tailrace end. The document uses over 20 before and after photographs to demonstrate the impact of the flood on the various parts of the 25 MW hydroelectric project.
