Depending on how much you have to spend and what you want to do...

I'd recommend heading up to the Bristol Bay area with your pontoons. From Dillingham or King Salmon, hire a float plane, and have them take you to the Moraine. There are a couple of lakes that they can drop you off from. One as I recall is called Mosquito lake. Hike up over a ridge and down on to the river.

The Moraine is about the size of the North Fork Stilly in the late summer months. By the last week of July the Sockeye will have started to keel over, and line the bed of the river with their carcasses, 2 to 3 feet thick in places.

There are VERY large rainbow in this system, 25 to 35 inch fish are not uncommon. Usually when you see pictures of trophy rainbow from Alaska, a good portion of them come from the American or the Moraine. The fish will remind you of steelhead in their fight and weight.

A good day fishing on the Moraine can yeild 20 to 30 fish hookups. A bad day would be just a couple, and there can be bad days to be realistic.

Do not fish these fish like you fish trout. They aren't JUST trout. If you leave a gaggle of line lying about your feet you won't be landing fish! These things take off like rockets!

A technique that guides on this system use to insure their clients get hookups is to stand up stream of their clients and work their feet up and down in the carcasses above a riffle with a deep hole on the backside. This will yeild a feeding frenzy in the hole as the meat from the carcasses spills over the riffle. The result is pretty predictable. HOLD ON and ENJOY!

To fish this 'hatch', tie on a 1/0 Tiemco 7999 barbless with a cream white bunny hair leech over about 1/4 oz of lead wrapped up the shank of the hook. Use about a 6 to 8 lb flourocarbon leader (Seaguar). This is referred to as a flesh fly. Other patterns you better have handy would be deerhair mice, sculpin, egg-sucking-leech, leech, egg puffs. All except the deerhair mouse should be weighted flys. I know they are a pain in the arse to cast but they do help getting down quick.

Hope this gives you some ideas. Oh yeah there is also the Alagnak River, the Brooks River (as seen on TV - where the bears are eating salmon at the falls), Naknek River, Brooks Lake, etc, etc.

The Moraine is a one day float, the Brooks a one day hike, the Alagnak could be strung out to be a week or more as it's about eleven miles long and flows from, if I recall correctly, Nonvionik Lake.

If you want more info about this area let me know by email (use my profile). I used to guide it.
