For some midsummer fishing that's a little out of the ordinary, try the Naselle River off State Highway 4 on Willapa Bay. Sea-run cutthroats inhabit the tidal portion of the river that extends about two miles upstream from the bay. August and September are prime months. Fish the incoming tide, because the flood brings invertebrates in from the bay and floods insects out of the vegetation, putting the cutts in a feeding mood. Good lures are Kastmaster spoons and Colorado spinners garnished with worms-only single barbless hooks are legal. For flyfishermen, dry flies such as Yellow Humpies and Adams Parachutes are proven patterns, along with Woolly Buggers in black and brown. A 6- or 7-weight outfit is just right. Most of the bright sea-run trout are in the 14- to 16-inch class. This cutthroat fishery is one of the best in the Pacific Northwest, thanks to the catch-and-release-only regulations that have been in effect for two years. A resident freshwater fishing license is $20; nonresidents pay $40 for the season. A two-day license for residents or nonresidents is $6.
