- While it was called an arrastre, a dam is only a part of an arrastre. The dam diverted water to power a horizontal water wheel that dragged heavy stones which ground ore into fine particles to facilitate gold removal. Arrestre's originated in Mexico where burros, walking in a never-ending circle, were used instead of water power.
- The original Virginia Turnpike crossed a bridge over Kentucky Creek about thirty yards upstream from today's Kentucky Creek bridge and took a short turn into the walls of the turnpike as we see them today. THe concrete abutments are intact but covered with blackberry bushes and difficult to get to. Stone walls of the original road can be seen across the road from the cemetery above where Pleasant Valley Road now cuts thorough it. Consequently there was no road under the flume at the time, the height being necessary only for the pressure needed for mining purposes.
- See Deadfalls Ditch for the Grade House location.
- Robber's Rock was so named because a stage coach was once robbed at this curve and the thieves hid behind the rock in order to waylay it. The rock is located 0.8 miles south of Bridgeport on the left of a sharp curve on Pleasant Valley Road.
