Scotch some of the best fishing I ever had was near a dredging operation! The bass would come in every night after the job shut down and go nuts for all the little critters that had been moved up out of the mud And the bait fish that came in after all the small stuff!!!!!
I'll give you one of my old tricks another great place is near any quahog diggers off shore as this also kicks up the bottom and starts up the food chain in high gear!!!
