As everyone knows, Beach House and crew always transit any ICW problem areas exactly at low tide. That way we don't have to hurt our brain figuring out depths at mean low water. Today was no exception as we traveled through Lockwoods Folly and Shallotte Inlet. Here is a report on what we found for depths as we travel south on the ICW.
Lockwoods Folly We found plenty of depth favoring the red side until we arrived at the inlet from the north. At green "33" depths were about 18 feet. At red "36" we favored the red side and found 14 feet. As we passed "36" the depths came up to 11 to 12 feet. Still favoring the red side, as we approached green "39" the depths were 10 feet. Passing green "39" at mid channel we found 20 feet. At red "40" we found 17 feet at mid channel. Passing red "42" mid channel we had 14 feet. As we approached the floaters we favored red marker "46A," stood off about 20 feet and found 10 feet. From red "46A" to red "48" we found 6.2 feet very briefly, then depths returned to 7 feet, then 8 feet as we passed green "47A." As we passed red "48" the depths dropped off to 9 feet until just before we reached the first pier passed the inlet where we encountered only 6.9 feet mid channel. Once past the first pier the depths dropped to 12 feet and all was good.
Shallotte Inlet This was the surprise. Coming north a few months ago we had no problems. As we approached the inlet from the north we favored the ocean side from green "71" to "75". At red "76" we passed about 30 feet off the marker and found 13.5 feet. At green "77" mid channel depth was 18 feet. At red "78" mid channel reading was 17 feet. At red "80" about 15 feet off marker it was 17.5 feet. At red "80A" we were 10 feet from the marker with 8.9 feet of depth. Just past "80A" depths dropped to 12 feet. At mid channel between red "80" and green "81" the depths suddenly came up to 5.3 feet. Reaching green "81" about 50 feet from the marker we found depths of 9.8. At red "82" about 30 feet off the marker, depths were 10.9 feet. After passing red "82" by about 50 feet, depths dropped to 15 feet. From that point on it was smooth sailing, or motoring, depending on your perspective. All depths were at low tide for the day. We hope this will be of value to those that follow in our wake. We'll keep everyone posted of any issues as we move south.
