I have always wanted to put my boat in at the Harrison Ave. ramp,but several people have told me not to put in there unless I've got somebody with me that knows the area.They said there are shallow rocky ledges that will rip your lower unit off! Can anyone give me a description on where to go or where not to go? Or,if someone that knows the area would like to go with me and show me I would really appreciate it! I would just like to fish the lower spillway and hydro, I'm not worried about going up into the falls.
