RedactedNarrative: I was running at about 15 miles per hour pulling a kneeboard in an area where other boats were running. The depth guage was indicating the water levels between 21-44 feet. We struck something ( I believe was a rock) and the water depth jumped to 4 feet. I presume there must have been a point of land that jutted out into the water that has been covered by water.
