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. 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.

The identification coding on these photographs can be interpreted as follows:

• The largest number on the leftmost side is the frame number for the individual photograph.
• The following code to the right in the format "B) 70-38" is currently unknown, but may refer to an internal project number for the Lockwood Survey Corporation.
• The 6" may refer to the camera's focal length in inches.
• Next is "17,150 ASL" which is 17,150 feet Above Sea Level.
• Following is "152.63" which refers to the camera's focal length in millimeters, which equals 6 inches.
• The "W1339" may refer to the reel, but that is unconfirmed.
• "1 AUG 70" is the date the photos were taken.
