There is no doubt that the bass in less pressured bodies of water are easier to catch than bass from a highly pressured body of water, but the bass might be bigger in a highly pressured place. Those bigger bass become quite good at evading most if not all fishermen since they had a long life to learn fishermen are no good for them. There are a couple public bodies of water I fish down here where I have caught several +8 pounders ( including some over 10 pounds) and most people never catch a single bass over 8 pounds from these places. You have to know how to read the conditions on any particular day and know what to use to get these big bass to bite. Putting the time on the water is what has helped me the most, and its the same for most good bass fishermen I know. Private waters is different, its like shooting fish in a barrel and not much of a challenge to fish those places. Watch your surroundings when you fish, keep safe, and most importantly have fun.
