Abraham Lake
A chinook arch forms above Abraham Lake, Alberta.<br />
<br />
Abraham Lake was created by the damming of the North Saskatchewan River, in the foothills of the Canadian Rockies. It is accessible via the David Thompson Highway (Alberta Highway 11) east of Banff National Park, between Saskatchewan River Crossing and Nordegg.<br />
<br />
The lake, covering approximately 5300 hectares, was created in 1972, with the construction of the Bighorn Dam. It was named for Silas Abraham, an inhabitant of the Saskatchewan River valley in the nineteenth century.<br />
<br />
Although the lake is man-made, it has the blue color characteristic of other glacial lakes in the Rocky Mountains, which is caused by rock flour dispersed in the water.
