Latest fishing report
Fall outlook: for boat and shore anglers alike, trout fishing is usually best at shallow to middle depths. From shore, rainbow trout can be fished with a worm or dough bait on the bottom of the shallows, while for cutthroat, tiger trout and splake the most effective approach is to cast and retrieve sinking flies, jigs, crankbaits or inline spinners. Boaters can do well with all four species by trolling crankbaits that dive to shallow or medium depths, pop gear with a worm, or a dodger paired with a squid.
Trout from 15 to 22 inches must be released immediately; kokanee are not covered by this slot limit.
