On Friday's search, I spent about 4 hours on the water conducting a Bottom Current Flow Test, continuing to record sonar data to review, and created a new depth chart of the area.
This is the Seven Sisters Boat Ramp that is now privately owned. The large dock and yachts to the left did not exist when Haleigh went missing.
I placed the float test rig in the water a short distance from the dock at the ramp. The St Johns River is affected by tides and at this time, it was high tide. The current in the area was practically non-existent. I'll need to do a flow test at low tide when the current flow will be at it's greatest.
Here is an image that shows the waters downriver of the boat ramp. The yellow circle is about where the deep hole is.
About the time Haleigh would have gone missing, it was approaching high tide, 3:24am. By 10am, it was low tide and at max current. This would occur before divers searched around the boat ramp.
Here is the new depth chart I created. This took several hours to create while I was recording sonar. The boat icon is at the boat ramp.
I am still reviewing hours of recorded sonar and have numerous targets of interest. Here you can see examples. Most of these targets will be natural debris. Some will be man made debris such as coolers. In a lake in NC, I found a home safe about the size of a small refrigerator. You never know what you'll find until you look.
I have a very important engagement for several days this week on another case that I have been working on in this area for about a year. I hope to be able to make an announcement here on Websleuths soon about this other case.
My next search for Haleigh will be on February 10th. Yes, I understand the significance of that date. I have videos of my search efforts on my FB page. I'm not sure if I can post the link here. DM me if interested.
