CANAL EXITING TUNNEL (LEFT BACKGROUND) IN PLATTE RIVER CANYON, WITH LATERAL GATES IN RIGHT FOREGROUND. VIEW TO WEST - High Line Canal, Mouth of South Platte River to confluence

From the Historic American Engineering Record's survey of High Line Canal. The photographer's own caption is the title above.

Shows: High Line Canal as the survey found it, in the frame the survey chose.

What this does not let you conclude: The structure's present condition, or how much water it carries today; the record beside it carries the numbers. HAER surveyed what was standing, not what was decreed. HAER's compilation date; the photograph itself is undated in the record.
