I fished on Thurs morning from Jonas Green park. I fished College Creek and two other nearby areas that usually hold summer perch. The water looked an unhealthy brown color. In 2.5 hours of casting to shorelines, I caught about 5 perch and one pickerel. So your lack of success may have been attributable to the poor water quality that day (if that makes you feel any better).
Last Mon evening, I did much better in the upper half of Weems Creek. It often takes some looking around to see where the fish are biting that day. Also, don't hesitate to try different lures with different functional features (for example try some spinner-type lures and try some soft plastic lures to give the fish a different look). When you first start out in a new area, you have a lot to learn. The more times you fish the same areas, you will gain confidence on what will work and which sections of shorelines or which drop offs are the most productive ones.
