I live a few miles from where you speak of, it is "the Econ" only accessible by kayak or canoe from the snow hill area & downstream... many tree lay-downs to maneuver around with a few deep holes, but mainly shallow through-out. Very popular with the younger crowd on the weekends. However, if you launch from Rt. 46 at C.S. Lee park, the Econ starts about 3/4 to a mile on the right hand side headed south & is boat accessible for a good 6-8 mile stretch & maybe where these reports you have heard, come from. Good luck & catch a bunch....also you can use any size motor on the Econ, but would just not be feasible in the Snow Hill area & downstream to protect your lower unit. Trolling motor wouldn't get you back through current around Snow Hill, many drop off at Snow Hill & have another vehicle parked downstream in Oviedo to end canoe or Kayak trip, beautiful wild life area......
