Latest fishing report
Fall outlook: trout fishing is usually best at shallow to middle depths. Shore anglers do well with dough bait or worms for rainbows and with flies, crankbaits, jigs and spinners for cutthroat, tigers and splake. Trollers can use crankbaits, pop gear or squid and dodger. Release all trout from 15 to 22 inches; kokanee are exempt.
