Try fishing off of the docks at the various city parks along the Tualatin River. Any slow moving water is bound have panfish and possibly crappie in that River. There are some parks in Tualatin, Tigard. and Sherwood -- Just check out satellite view on google maps.
Caught at Cottage Grove Lake 04/21 near floating debris on a black and blue finesse jig with a craw trailer. Slow fishing in at Dorena and CG Lake this weekend but this one bite made my trip.
