Hi Les;
I live about an hour southwest of Portland. I have not fished that area in over 20 years (I have enough fishing here) So I am of little help, but I will say the water is very warm this time of year, so I don't target trout till at least Sept. Most people fish smallies right now or stripers in the salt.
You may find better info on this forum. Good luck and tight lines
