The river flows from Tangent, and under Hwy. 34...just a bit east of Oakville Rd. It flows through farmland in the stretch from Hwy. 34 to SW Queen Ave. Then river flows a few more miles and into West Albany. The Sodom's Ditch dumps into the Calapooia, just before the 3rd St. bridge. Then about a 1/2 mile more, and the Cally flows into the Willy, by Monteith (SP?) Riverfront Park (Bryant Park is on the west side of the stream).
A buddy and I worked our way upstream from Queen a few times, back in the mid 80's. We caught some smallies and one bucketmouth. We also caught small trout and dozens of cats below the Queen bridge. The cats were 8 - 12", and can be found about 100 yards downstream from that bridge. Easy pickin's!
