I remember that there's a large pond behind OES when I passed by there. I found it on local.live.com (its graphics are better than google maps) and it didn't look bad. I looked online and found out that it is the scource of Fanno Creek, which empties into the tualatin river. Fanno Creek is where the Bass spawn. I doubt you can fish in it. I also found that there are ducks, minnow, bugs, and weird insects living there since it is a huge wetlands with a pond. Looks huge if you drive by. I don't want to get in trouble though by fishing.
