Fall of Reach
- Main article: Battle of Viery
On the night of August 11, 2552, Recon Team Bravo discovered a team of Colonial Militia fighting off the Covenant in the upper part of the facility. After assisting them, Recon Team Bravo traveled down to where the Covenant pylon was and planted explosives on it.
This power plant was located in a barren and mountainous region of Reach, on a mountain ridge overlooking a desert basin. A dam was constructed in a narrow canyon not far from the cliff edge. With the dam in place, most of the river's former bed below it had turned into dry land, where the power station had also been constructed. A small fraction of the river ran through the facility, down to the bottom of the basin, where the river had eroded a wide and deep canyon, which now had water only in its very bottom.
