River Tay
The River Tay emerges from Loch Tay at Kenmore, and flows from there to Perth which, in historical times, was its lowest bridging point. Below Perth the river becomes tidal and enters the Firth of Tay. The largest city on the river, Dundee, lies on the north bank of the Firth. On reaching the North Sea, the River Tay has flowed from west to east across central Scotland.
Tye River
The Tye River is home to dozens of species of fish and other aquatic life, including American eels, small and largemouth bass, and native mussels. A dam was removed in 2007 to help facilitate fish migration. According to an official of the Virginia Department of Game and Inland Fisheries, "Removing the dam will increase the passage possibilities, and hopefully the populations of all these species. It will also allow for increased access for anglers, paddlers and boaters."
