These historically important aerial photographs depict Williston Lake soon after its creation in 1968 with the building of the W.A.C. Bennett Dam on the Peace River. Also depicted are the rivers and tributaries that empty into the Williston Reservoir, such as the Finlay River, the Ospika River, and the Omineca River.

These remote-sensing aerial photographs were taken by Lockwood Survey Corporation Ltd. under contract for the B.C. Forest Service. Some photographs are annotated to show logging activity; clearcuts, slash piles, log booms, and tree debris on the water are also visible in some of the images. No detailed location information or index accompanies the photographs.
