If you line by monroe like i do you would be amazed at all the sloughs and farm ponds. I can drive dawson and ingram island road alone and fish 10 different boddies of water. Most have trout, bass, carp, bluegill, crappie, and catfish.
They all get feed by the long tom/ willamette so there are crazy fish in them. I catch smallmouth out of the longtom, and my buddy caught a 2 lb crappie.
