Where next?

Newbie looking for hikes (preferably loops) within a 90 minute drive of Portland/vancouver that fall within the following perimeters:
-- Dog friendly
-- NW Forest Pass
-- Multiple, I do mean multiple, water sources
-- Minimum of 2 miles
-- Easy to moderate in difficulty. Siouxon Creek #130, between the trailhead and junction #130A, is an ideal example of the level of difficulty in terrian/altitude gain I would like to have in a hike.

I am also looking for someone who would like to join me on some adventures. I leisurely walk, stopping and looking at everything; not in any hurry to reach the destination, just livin' in the moment.

Thanks.
