Blackfoot River Outfitters's Tip of the Week

The fall months are a great time to be at Georgetown. As the weather starts to cool off the fish will be cruising shallow warmer water. Along with the cool weather fishing will start to turn to mainly subsurface fishing. If the lake turns to glass, throw a small streamer or strip a leech instead of an indicator rig. ***Open third Saturday in May through March 31, except for the South and East shoreline area which is only open July 1 through March 31. South and East shoreline areas described as follows: all waters from the shore or within 100 yards of shore in the area extending from a point 200 yards west of Lakeside at Georgetown Marina (along the shore, including all of Stuart Mill Bay)***

5-Day Outlook as of 9/25/26

Fall has hit Georgetown! The weather this weekend is going to have highs in the 50s with overnight lows in the low 30s with lots of cloud cover. The rest of the week is going to be very similar to the weekend with highs in the 50s with overnight lows in the low 30s. More sunshine throughout the week.

Techniques & Tips as of 9/25/26

In the afternoons there is a chance of some dry fly action with small callibaetis and mayfly patterns. Fishing primarily has moved subsurface with an indicator rig. A balanced leech and scud patterns are your best bet. An attractor nymph like a Pheasant Tail, Hares Ear or Frenchie can also work. If the lake is very calm, strip a balanced leech, wooly bugger or a small streamer.

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.
