The Smallwood Reservoir is a reservoir in the central east of the Labrador Peninsula in the Canadian province of Newfoundland and Labrador .

Reservoir

The reservoir was created between 1967 and 1971 through the construction of 88 dikes with a total length of 64 km. The lakes Lobstick Lake (western part of the reservoir) and Michikamau (eastern part of the reservoir), which were located on the upper reaches of the Churchill River, were flooded. In addition, part of the catchment areas of the Kanairiktok River and Naskaupi River were incorporated into the reservoir by building dams. The reservoir extends over an area of 5698 km² (including islands 6286 km²). The lake was named in honor of Joey Smallwood , the first Prime Minister of the Province of Newfoundland and Labrador. The Smallwood Reservoir is mainly fed by the Ashuanipi River and via the Gabbro Control Structure from the adjacent Ossokmanuan Reservoir to the south . In normal damming, the water level is 472.74 m . The maximum water height is 473.66 m .

At the Lobstick Control Structure ( ⊙ ) discharge control structure , the water flows from the Smallwood Reservoir into the West Forebay ( ⊙ 451.1 m ). From there, the water passes through the Whitefish Control Structure ( ⊙ ) into the East Forebay ( ⊙ 446.2 m ) and from there to the Churchill Falls hydropower station . During flooding, some of the water flows through the Jacopie Spillway flood relief system ( ⊙ ) on the south bank of the West Forebay into the original river bed of the Churchill River and then passes the Churchill Falls waterfall . On the east bank of the East Forebay there is another flood relief, the Forebay Spillway ( ⊙ ). 53.869052 -65.03145753.684976 -64.41612 53.639462 -64.26975353.59643 -64.006193 53.650131 -64.37324353.567907 -63.910873
