River Wye is a limestone river in the Peak District of Derbyshire, England. It is 15 miles long and is one of the major tributaries of the River Derwent, which flows into the River Trent, and ultimately into the Humber and the North Sea.
The river's source lies just west of Buxton, on Axe Edge Moor. Part of the flow passes underground through Poole's Cavern before rising at Wye Head, then flowing through the Pavilion Gardens in Buxton. It then flows east, along a route roughly followed by the A6 road. It enters the Peak District, flows just south of Tideswell, then through Ashford in the Water and Bakewell, and south of Haddon Hall, before meeting the River Derwent at Rowsley.
The River Lathkill is the main tributary of the river, which enters approximately one mile from its mouth.
The River Wye is one of Derbyshire's best known rivers and is popular with anglers owing to the large numbers of wild brown, rainbow trout and grayling it contains. The alkalinity of the Wye provides a rich source of nutrients that leads to an abundance of insects, invertebrates and other wildlife. This ensures that the trout and grayling grow quickly on a diet of freshwater shrimp, sedge and up winged flies. Some of the largest populations of water voles in Britain can also be found along the River Wye.
