Reports of shoaling south of Fernandina Beach have been coming in for several years and prompted a USCG Hazard Warning in May of last year (/?p=140702). Our thanks to geologist, Bill Aley, for sending these surveys to assist in guiding you through the shoals. See /?p=153488 for further advice.
And, thanks to Robert Sherer, we have the lat/lon locations of the turns indicated in the survey below with WP1 being the first heading south:
Note corrections to WP 2 and 4 below, thanks to Mike. Note also that our chart centers on WP 4.
This posting is what prompted me to email Taylor Engineering asking for more detail, namely the waypoints for the route turns. I wanted his numbers rather than trying to interpolate from the chart. He was gracious enough to provide them. Perhaps we can nail this section of the ICW so it will never again cause agitation for boaters!
At the request of the Florida Inland Navigation District (FIND), I’d like to share the attached figure with you. The figure illustrates an area of shoaling in the Atlantic Intracoastal Waterway within Nassau County, FL that is a potential navigation hazard.
The PDF file depicts some very recent mapping that shows naturally deep water to the west and south of the currently marked channel in this area. Taylor Engineering is currently working with the FIND, US Army Corps of Engineers, and US Coast Guard to relocate the federal channel and corresponding red channel marker #18 and green channel marker #1 to direct navigation traffic towards the deeper waters.
