  • Depth: Likely within recreational diving depths, approximately 30 to 130 feet (9 to 40 meters)

Vessel Type Description

The D21 Wreck is an unidentified shipwreck discovered near Oswego, New York, during NOAA’s 2022 survey of Lake Ontario. Its type, size, and materials remain undetermined. Given the region’s maritime history, the wreck could be a commercial vessel, fishing boat, or military craft. These types of vessels were critical to trade, industry, and defense in the Great Lakes during various historical periods.

History

Oswego’s waters have been a focal point of maritime activity for centuries, serving as a hub for trade, transportation, and military operations. The D21 Wreck likely played a role in these bustling waterways, although its specific history is unclear due to a lack of identifying features or historical records.

Lake Ontario has witnessed thousands of shipwrecks caused by storms, collisions, or navigational errors. The D21 Wreck could be from any number of historical periods, making it a valuable subject for further study. Its discovery contributes to our understanding of the diverse array of vessels that navigated the lake, each with its unique story tied to the economic and cultural development of the region.

Final Disposition

The D21 Wreck lies undisturbed on the lakebed, likely within recreational diving depths. The extent of its preservation is not well-documented, leaving open questions about its condition and the events leading to its sinking. Further research and exploration are required to uncover its story and historical significance.
