POS. 42 33.2N, 082 35.2W *****SOURCE UNKNOWN–CHARTING STATUS CHANGED TO EXISTANCE DOUBTFUL (ED) ON 1990 EDITION OF 14852 PROBABLE SOURCE IS COE ‘AUTO SWEEP SURVEY’, 1986. H11913: OPR-W408-NRT4-08; AWOIS #10702 not investigated during this survey. (Updated 6/17/09 KAK).”
This information suggests that the wreck was reported in the Local Notice to Mariners (LNM) in 1978 by the 9th Coast Guard District. It is described as a 14-foot outboard boat sunk at approximately 42°33.2’N, 082°35.2’W. The charting status of the wreck was later changed to “existence doubtful” (ED) on the 1990 edition of chart 14852. The probable source for this change is attributed to the U.S. Army Corps of Engineers (COE) “Auto Sweep Survey” conducted in 1986. As of the update on June 17, 2009, the wreck had not been investigated during a specific survey conducted under OPR-W408-NRT4-08.
Due to the submerged wreck being labeled as “dangerous to surface navigation” and the charting status being “existence doubtful,” mariners and authorities should exercise caution in the area and consider the wreck’s potential presence while navigating.
