Hi Carrie,
Here are the basics for navigating Spring Lake on your Saturday tour. When you are in Deep Hole have the main spring on your left side and move west. You will get to Fault Line, the next big high pressure spring in Deep Hole. Look up and west and you should see the channel into Arch Site.
From Arch Site head in a northwesterly direction till you see the pilings for the dock. From there you will turn right and maintain around a 6 to 8' depth keeping the bank on your left side. When you see the second big patch of Arrow Root start looking to your right at about 2 o'clock and look for the "deeper blue" in Catfish.
The run from Catfish to Cream of Wheat is on a 50/230 bearing. At the head of Riverbed there is a big cypress log. Just past the log, up and to your left is the deep channel into Ossified Forrest. At the top of Ossified Forrest the deep channel is to your right. You will know that you are in the right place if you see a tree limb sticking out of the mud parrell to the bottom (hard to miss). You ALWAYS enter Ossified Forrest on your left side and exit on your right side. If you take the opposite route into/out of OF you get very shallow very fast and you are right where the boats transit.
Once you are over that hump you are in Little Riverbed/Cream of Wheat. From there you go to Diversion and you can enter the Training Area by either going around the old submarine theatre to the left of the pipe at Diversion or you can go under it to the right of the pipe.
Hope my directions make sense and have a great time.
