Dowty Road.
Real close to the Chevron in Eagle Creek(just before you turn into the gas station,look to your right)
Take a right on Dowty,then follow the road to the right about at your first opportunity.Stay on that road, through a small series of S-turns, then you should come to a small bridge that takes you over the creek.Parking is on the right, just after crossing the bridge.Should take about 5 or 6 minutes after turning off the main highway.
Lots of holes to fish inside the creek, on the way to the mouth on the Clack. Just follow the trails through the park, most follow the creek.It's about a 10 minute or so walk to the mouth of the creek where it dumps into the Clack, and waders would not be a bad idea(used to be necessary in years past when the water was a little higher like it is now).
Roads are fine, some fish are around.
Tight Lines,
