FishOn, the light is the Toledo light, big brown gorgeous brick structure with a repetitive fog horn, marking the W side of the ditch. Turtle Island is E of the light approx. 2-3 miles. There is a series of humps & some structure from spoils, current, etc. It will shallow up to 7' as you get closer to the Island, did well there yesterday in 9' of water W of the pack, hope this helps.
