Blackfoot River Outfitters's Tip of the Week

Subsurface has been the most productive way to catch fish with this warm weather we've been having. The damsel's and callibaetis haven't really started hatching yet. In the evenings the sedges are out but the fish haven't keyed into them yet.

Description: About Georgetown Lake

Georgetown Lake is Montana’s premier flatwater fishery. Rimmed by the Anaconda Mountains (aka Pintlers), it’s also among the state’s most beautiful. But the real attraction is rainbow trout in the 16"- 26" range. Yes, we said 26" rainbows. As if these giant rainbows weren’t enough – there are numbers of brook trout over 16” and many exceeding 20”! You don’t need to travel to Labrador to see fish like this – they live here - and plenty of them. The special regulations imposed now over a decade ago, continue to pay huge dividends. Much of the lake shore is closed to fishing before July 1st to maximize rainbows’ opportunity to grow well into maturity and you must return all brookies to the water immediately. As the water warms in June, these leviathans fresh off the spawn gorge themselves on damsel fly nymphs, leaches, crane fly larva, scuds and midge pupa. Pitch small buggers and leaches to single cruisers and across spring holes through the month. Later in July, continuing on into September, you can fish a nymph or streamer but try sight fishing to them in just inches to a few feet of water. If you’re a saltwater angler, it will remind you of polling the flats scanning for bones, but instead of them rooting out crabs they are toilet bowling dries on the surface. Blanketing damsel fly hatches, early morning callibaetis, gulping midge clusters and the giant olive sedge skating across the water just before dark are the occurrences you don’t want to miss! There is nothing else quite like it in Montana.
