On the South Amelia River between red markers "34" and "36," we found 7 feet of water in the channel. With the tide state at the time we transited, the depths would only be 4 1/2 feet at low tide. Enough draft for us to pass, but barely. Boats with deeper drafts would surely be grounded. A little farther along between green markers "39" and "41," our depths were 9 feet, making it 5 1/2 feet at low tide. There were several areas that would only be 6 to 7 feet at low tide in the same area. It had been several years since we transited this section of the waterway. With our former sailboat, Sea Trek, we always transited between the St. Mary's River and St. Augustine on the outside, waiting for good weather if we had to. Another reason to not have to keep a schedule. Maybe it was time for us to do another inside run to get familiar with changes along this section of the waterway.
