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 (Washington)
The Tye River is used by chinook and coho salmon. Adults migrate upstream as far as Alpine Falls. Spawning occurs mostly in the mainstem river. Some coho spawn in the lower parts of a few tributary streams such as Alpine Creek. Juvenile salmon rear throughout the accessible waters of the river basin. No anadromous fish are found above Alpine Falls as it is a total barrier to fish migration. Sunset Falls on the South Fork Skykomish River, below the mouth of the Tye River, is also a total barrier to fish migration. All anadrmous fish above Sunset Falls, which includes the entire Tye River basin, are present only as a result of a trap and haul operation initiated in 1958 by the Washington Department of Fisheries. Between July and December fish are trapped below the falls, trucked above, and returned to the South Fork Skykomish.
