babs2009, do you have any directions on how to get to any of those lakes? I'm not finding any of them on google. Thanks for the info!
Blue lake is in between Marine Drive and I84 towards Troutdale. Smallish lake, not a dog friendly park, never fished there but it is stocked with rainbows. And there is a Triathlon run there in June.
Benson Lake Rec area at exit 30 along east bound I84, stocked with rainbows and has warm water fishery as well (scouted yesterday). Benson lake is very shallow out to at least 20 yards from shore, from the looks of things it is best fished from a float, although I am going back out with my waders to try my luck.
Hagg Lake (Scoggins valley rec area) is always a safe bet, along Hwy 47 enroute to Gaston out of Forest Grove.
Later in the season Faraday Lake just past Estacada has some decent fishing off the dam
I haven't tried Bybee lake, so I'm not sure of what to expect up there.
Haldeman pond on Sauvie Island is worth a shot, although it is about the opposite of scenic.
