"Originally constructed in 1843, the aqueduct was partially destroyed by a flood in 1846. Shortly afterward, it was rebuilt with a modified Burr arch truss more than 75 feet long. The Duck Creek Aqueduct is very unique — so much so that it was featured in an edition of Ripley’s Believe It Or Not. It is perhaps the only covered wooden aqueduct still operating in the United States. Engineers designed this aqueduct to carry the canal and its boats above Duck Creek. It’s on the National Register of Historic Places and is a National Historic Civil Engineering Landmark."

"A 'tumble' acts like a spillway on a lake, allowing excess water to bypass a lock in the canal. Without a bypass water would pool behind the lock and spill over the banks of the canal as water by gravity flows from higher to a lower level."

[The date was June 2010. It certainly had a lot better flow back then than I caught with the Jul 2020 Street View above.]

The second type of aqueduct was the enclosed or covered bridge type. The construction is the same as the open trunk. Then the structure is enclosed with a wooden frame above to protect the timber frame that is exposed to weathering in the open trunk style. There is a total of 20 aqueducts on the Wabash & Erie Canal in Indiana, but only 5 were roofed and enclosed. The longest, 510 feet long, was across the White River near Petersburg. It was roofed. On the Whitewater Canal there were 2 aqueducts. One crossed the Whitewater River just south of Laurel, and the next was at Duck Creek as shown in the photo below [above].
Kirk Patrick Shorter: There is a 3rd on the canal.... very small & easily missed. It is at the area of Goose Creek.
