Otter Falls on the Aishihik River

The Aishihik River is a right tributary of Dezadeash River in the Yukon Territory in Canada .

The river forms the almost 2 km long drain of Aishihik Lake to the elongated 11.8 km long Canyon Lake to the south . Both lakes are regulated by control structures. He then overcomes Otter Falls , a waterfall depicted on the back of Canadian 5 dollar bills in 1954. The river later takes on the right tributary West Aishihik River . Shortly before the mouth at Canyon Creek , the Yukon Highway 1 ( Alaska Highway ) crosses the river. One of the original wooden bridges on the Alaska Highway still stands here.

Aishihik hydroelectric power station

The Aishihik hydropower plant was built in 1975. Aishihik Lake and Canyon Lake, together with the upstream Sekulmun Lake, serve as water reservoirs during the low-flow period in winter and spring. The water to the underground Aishihik power plant is diverted from the southern end of Canyon Lake via a 5.8 km long above-ground power plant channel. The used drop height is 175 m. The power plant has two 15 MW turbines and, since 2011, one 7 MW turbine. The water leaves the power plant via a 1.5 km long drainage tunnel to the West Aishihik River , via which it enters the lower reaches of the Aishihik River.
