Big Lost River

The Big Lost River becomes a popular fishery this time of year as snow melt increases to give some access below Mackay Dam. Midge and BWO activity makes for good fishing. The Mackay area got hammered with about a foot of snow this last weekend, but the river below the dam is accessible where some snow banks remain. Flow out of Mackay Dam was increased to 320 cfs last Tuesday.
Fly Patterns to use:
