Excellent fishing over in heritage farm ponds. If you can find the one with the big white gazebo, fish that one. Many 3+ lb bass caught in there. When it gets a little cooler it will pick up, but the fishing over there is really good. Great crappie to, you just have to know where. The fishing is slow over there right now, but it will pick up. This is a satellite image of the lake, so you can get an idea of the one I am talking about. http://maps.google.com/maps?q=lisle,+il ... &t=h&hl=en
Go there, give it some time, its a great local place. We have always had sucess with senkos in there. Never fished for cats in there. Use the zoom on the picture and it will go right to the lake.
