If you want to beat cabin there are great opportunities. Here are some random angling reports from the past week. Some are typical fishing spots for this time of year, but others may cause you to say, "why didn't I think of that?"
Cascade is "spotty" at best. People are catching a few large perch and rainbow trout through the ice. If you are looking for qualilty and not quantity - Poison Creek is a good spot. Sugarloaf has produced a few more trout but you need a snowmachine to access the reservoir.
Payette Lake as been yielding lake trout. I've seen several in the 20" - 30" range. Jig just off the bottom in deeper water areas (upper 2/3 of the lake). Be careful on the edge of the ice because it is still a little soft.
Salmon Falls Creek Reservoir has produced nice trout through the ice. Fish the bays, such as Gray's Landing with bait. Anglers are finding fish in 10' - 12' of water.
Magic Reservoir is fishing much like Cascade. Fishing has been "spotty" with some anglers being "skunked." Fish bait about 10 - 12' deep for best results.
LIttle Wood Reservoir is a fishery that has yielded nice catches of rainbow trout with most anglers reporting limits followed by catch-and-release action. You need a snowmachine to access the reservoir.
Warm Lake has been good fishing with several reports of anglers catching limits of rainbow trout. Again, you need a snowmobile. Use eggs, corn, worms or maggots for great results.
Mackay Reservoir is a great winter fishery - if you don't mind a slight breeze. Locals are catching rainbow, cutthroat and an occasional perch using bait.
Bank Anglers and Open Water:
C.J. Strike near Air Force Ramp and Cottonwood Boat Launch have both been reported as great locations to catch rainbow trout and perch. Anglers are reporting bait and lures both yielding great results. Lures (e.g. Dare Devil, Rooster tail) have been effective for rainbow trout.
Arrowrock and Lucky Peak have both been good from the bank. Rainbow trout limits are common using mostly bait (worms, corn, etc.).
