Blackfoot River Outfitters's Tip of the Week

Georgetown is still fishing well and is a great place to go find some cool water with our rivers getting hot. Fish are looking up for dry flies if that is Mayflies, Caddis or Terrestrials up there. Throw those flies right on top of weed beds or right on the edge of the drop offs. If the lake has a little too much chop strip some flies underneath the surface. ***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 7/24/26

The weather at Georgetown this weekend will be sunny and warm. Highs will be in the 80s with overnight lows in the 40s. The rest of the week looks to be the same. Highs in the 80s with lots of sunshine.

Techniques & Tips as of 7/24/26

Floating a terrestrial dry fly or a callibaetis dun near the weed beds or the drop offs. However, a two-fly indicator rig with a balanced leech and a scud or damselfly nymph suspended over the drop-offs remains an effective way to attract fish. Stripping a wooly bugger, damsel nymph or small jig streamer is another option if the fish aren’t looking up.

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.
