saw dust cove? never heard of it. For spring fishing any where in 4-6 feet of water (I'm serious). My fishing partner sits up front and warns of rocks or if it getting too shallow. We follow established gps tracks. The shoals run out a long way from shore so extreme caution is advised. A couple years back I ran my boat aground on that shoal at the south end of simms cove. Front of boat was in six inches of water and the back end was in 6 feet, never hit the motor and didn't do any damage as we were trolling. Can't wait for 01 May, however I'm not expecting a banner year because the ice will most likely let go any day now and with over a month to go the best fishing will be past by the time the season is open.
