Just saw this question…
I see bass boats in and around these areas all the time however I think the big boats enter these backwaters from below….come up from the big lake on the S’conie side. I put my jon in off the launching pad found at the second cement bridge and have to make my way out of that lagoon thru a small, very shallow cut. My short shaft 20 will tick rocks if I am not careful. This launch affords the most access to these waters, in my opinion.
I won’t say larger boats can’t launch, but I’d be darned careful about getting around until you find ample water.
