I don't know if dredging annually is going to happen as Fisheries and Oceans seem to be keeping an eye on such activity. I agree, follow someone who knows the route and when the tide is low use your kicker. Last year the route was: stay right around the first bend (a sand bar is just off to the left off the bend that seems to cause problems), stay in close on the right side of the bank, then aim for the docks, then aim for the bouys, and stay right as you pass the spit. Watch your sounder and don't be in a rush. I have found at low tides you have about 18 inches as well. Wait an hour after the begining of the flood if you can't get out as it takes at least that amount of time to see some rise and the flood means you are bucking the tide/flow going out.
