With flow out of Mackay Dam still close to 500 cfs, wading is limited. The flow is sure to drop, and make for easier wading to meet flav and terrestrial insect and later trico activity. Floating the river to fish is possible, and caddis, PMD, flav life cycle patterns will work. Likely some golden stoneflies remain. We will post decreases in flow here as soon as such happens.
Flows are still at 100 cfs. and the fishing is great! Good Blue Wing Olive hatches right now. Look for the hatch from 11-4. Cripples and emergers have been the best patterns for fooling fish. We don’t know when the water will go up on the Big Lost, however this river is accessible by wading up to 300 cfs.
With flow out of Mackay Dam just a bit above 100 cfs, wading is easy. Midges are active, and a few BWOs are emerging. Not much snow is around, and the days are warming up. Looks like all aspects are together for a trip to the Big Lost. Don’t forget those small bead head nymphs or size 12-14 bead head peacock leeches! Want more info on the Big Lost River? Take a look at the 3/19/13 offering on it in our web site Articles post.
The Big Lost has been picking up lately with the nice weather. Good midge hatches and very few Blue Wing Olives. I would continue to look for a BWO hatch any day now. Nymphing a prince nymph and Zebra midges has also been very productive. Don’t forget a few BWO nymphs. We have a great selection here in the shop.
Weather may bring an end to the comfortable fly fishing season here, but a trip to enjoy some top water fishing may be in order with flows out of Mackay Dam around the 100 cfs mark. Brookies and bows are responding well to BWO and midge activity. Small bead head nymphs are making for action, too.
With trico activity decreasing in the river below Mackay Dam, turn to BWO and midge life cycle patterns. Because of the canopy formed by cottonwood trees along much of the river here, one can expect good BWO activity even on brighter days. Flow out of the dam is a bit above the seasonal normal, but not enough to hinder wading.
