River Derwent

River Derwent, river in North Yorkshire, England, that rises on Fylingdales Moor only 6 miles (10 km) inland from the North Sea.

River Derwent flows more than 200 kilometers and drops more than 700 meters from its origin in the national park. It is formed by the collision of the Narcissus and Cuvier Rivers at Lake St. Clair and flows with the power of 50 to 140 m³ per second. It pours into a large estuary at the city of Hobart where you can find the deepest sheltered harbour in the Southern Hemisphere. Dams of the Derwent have caused 7 lakes to be formed -- Meadowbank, Cluny, Repulse, Catagunya, Wayatinah, Liapootah and King William. The river is important for hydroelectric power as well as for agriculture, forestry and fish hatcheries.
