Control Gates
This control gate regulates the amount of water flowing from Webster Lake through the CPW facility. While they have obviously been modernized, it is believed to occupy the same location as the original gate built by Slater & Tiffany in the early 1800s.

Water Trench
The water trench, too, has been modernize with concrete banks, but it still lies in the same location as it did almost 200 years ago. The first two pictures below show the water as it flows into the facility after crossing under Gore Road from the control gate shown above. The next two pictures show the trench as reemerges from under the factory on its way out of the complex.
