One of the best places to find big trout is where salmon are spawning. Trout or char will lay behind a spawning bed to voraciously consume eggs as they float by. With hundreds of salmon often representing four different species in a river at the same time, it can be tough to identify exactly what kind of eggs the trout are keying in on. Usually the trout will choose the largest egg. So find the largest species of salmon and target a female. When the fish is brought to the bank gently run your hand down her belly and check the color and size of the eggs. Match your fly or bait, and you’ll be in rainbow land in just a couple of casts.
