Columbia River. Kwikfish. Herring.

Best way to figure it out is to go out to the river and measure the OFI. What is the OFI, you ask? Why, it's the Old Fahrt Index, of course, which is the number of fisherfolk over the age of 45 times their average age, times the average age of their boats, divided by the average horsepower of the boats. Look for where the OFI is highest, and fish there. Watch where they fish, and what they do. Do it.

Seriously, in the springer fishery, look for the crowds. There aren't a lot of secrets about where the fish are.
