Tourist Drives in Western Australia are routes through areas of scenic or historic significance, designated by route markers with white numbers on a brown shield. Tourist Drives were introduced into Western Australia while Eric Charlton was the state government Minister for Transport in the 1990s. The 28 numbered routes collectively traverse more than 2,000 kilometres (1,200 mi) across the state. In addition to the Tourist Drives, there are unnumbered routes such as the Golden Pipeline Heritage Trail, and local governments may designate and maintain local scenic drives, generally unnamed and unnumbered.
Seneca Dam was the last in a series of dams proposed on the Potomac River in the area of the Great Falls of the Potomac. Apart from small-scale dams intended to divert water for municipal use in the District of Columbia and into the Chesapeake and Ohio Canal, no version of any scheme was ever built. In most cases the proposed reservoir would have extended upriver to Harpers Ferry, West Virginia. The project was part of a program of as many as sixteen major dams in the Potomac watershed, most of which were never built.
