basssin

ok i fish the Charles river dock in Watertown and i have been for the past 2 weeks every day for at least 1 hour each time and i havent even seen a bass yet should i leave it or no it looks good and all and it has bait fish perch sunfish and all that stuff and i might have seen people catch a bass there but ya. also this river is either murky or murky clear it has weeds and logs in the water i have already lost like 4 lures there and it has alot of green stuff that gets on my lures any tips i normally go there around 245 at latest arive around 4 and fish until 530 and no bass. i have fished it all top water senko crankbait spinnerbait crawfish and no action on anything at all except for some sunfish and 4 inch bass looking things that i can drop my lure right infront of them since they camp the dock and they will nibble it and swim away every time thats the most action i ever got. i dont know what to fish it anymore what lures to use how to use them and all that i think i need a complete refresh of knowlage and tips can yall help me out.
