Description

This wreck is an unidentified submerged hazard located in Lake St. Clair. It poses a danger to navigation, particularly for vessels with drafts exceeding 30 feet.

History

2006 (CL 1062): An uncharted wreck was identified by side scan sonar during operations by the National Ocean Service (NOS), Navigation Response Team 4 (NRT-4). The least depth over the wreck was found to be 9.95 meters, with the surrounding area depth recorded as 13 meters. The position of the wreck was recorded at 42°48’24.116″N, 82°28’54.131″W.

2008 (H11915 – OPR-W408-NRT4-08): The wreck was re-examined, and a new least depth of 9.3 meters (30.51 feet) was determined. It was recommended to delete the charted 32-foot dangerous sunken wreck and update it to reflect the new 30-foot dangerous sunken wreck in the corrected survey position of 42°48’24.0″N, 82°28’54.0″W.

2010 Update: This recommendation was entered into the database to ensure updated charts reflect the current depth and hazard status of the wreck.
