Herbert Jessen Public Boat ramp on Ashley River

Does anyone have any info to share on launching a 16 ft Jon boat with a 40 Yamaha at the Herbert Jessen Ramp, is it tide controlled that far up or maybe the depths are shallow etc maybe what and where to fish from the ramp. I live in Summerville and always fished the cooper but bushy park is so bad at low tide Iā€™m looking elsewhere . Thanks in advance for any info. Never launched there and looks a little sketchy. :+1:
