I have fished Wilsonville pond a few times, but have been pretty much unsuccessful. I know that there is bass in there along with trout and bluegills. The pond is usually really shallow, muddy and there is a lot of trash. Best of luck.
There is a dock at memorial park that you can fish from. Usually us worms either drop shotting or live worms hanging on the bottom. During the late summer I was nailing them on chartruse strike king spinners with a willow blade.
Last June(2009) I pulled out a 6-pound catfish. A month later my father-in-law got one that looked to be around 4 to 5 pounds right at the shore when his line broke. Unfortunately, we weren't quick enough to jump on it so it's probably still in there. All we used was chicken liver, night fishing with a lighted bobber.
