So there I am, first time on Seminole, following the channel heading north then back south and out to the east. Launched at the park on the SW side of the lake. My son and I drove past the dam and headed back to the dock after a morning of fishing and exploring. I'm following a 15' break line at about 3/4 throttle at the SW corner of the lake. I feel the boat shift slightly to one side...like it does when you're running a river and hit some sawgrass that has broken loose and is barely submerged. Look at the GPS and I'm in what is called a "depression" with 12' to 15' of water. Then I feel 2 more bumps and I start looking in the water off to the side and see several clumps of weeds...OH SNAP...I'm in 12' of water...and those aren't weeds. So I come out of it and hard the boat over to try and lay it on its pad without setting down in the water too much. I'm in the middle of a ton of trees...not a single one is above the surface. Not marked at all on the water...at one zoom setting on the GPS it says submerged trees (yeah about 1" submerged). I got the boat on the trailer and didn't see any damage to the 8 parts of the hull that are exposed...there are still 4 parts on the bunks. The LU and the prop are unscathed. Maybe I'm just lucky, but I was extremely beside myself at the time. How the F is that not marked anywhere. I guess I was used to every other stand of trees having a few above the surface. On a side note... I saw more alligators than bass...but I was fishing under bluebird skies with virtually no wind.
