Tidal creeks can vary in size from very small estuaries to wider creeks and flats that become shallow at low tide. The typical range for the term "tidal creek" regarding water depth is the depth at low tide can range from no water in the creek to up to three feet. So many of our tidal creeks are navigable in a small boat at low tide. I know the area and the creeks. So check with me on any property in the Bluffton SC area to find out if the property has some water access and the possibility of a dock.
