Big Lost River

Big Lost River 10-19-2009

Flow out of Mackay Dam is now less than 100 cfs. This means fish will be concentrated in deepest holes. During PMs they will come out for BWOs or midges, but this low flow makes them quite wary.


Big Lost River 10-15-2009

With flow out of Mackay Dam at 150 cfs, the river below is in great wading shape.  Midges and BWOS bring surface action, small bead head nymphs and soft hackled patterns bring action below.


Big Lost River 10-10-2009

With flows out of Mackay Dam just below 200 cfs and BWOs and midges active, this is one of the places to be fishing.   Look for these good conditions to hold into November.


Big Lost River 10-6-2009

With flows out of Mackay Dam at a bit over 200 cfs, the river below is very wadable. Tricos are past their peak, but BWOs and midges make for great top water fishing.  Small bead head nymphs always work.  Choose your favorite.  There is good public access just below the dam and at the campground downstream.


Big Lost River 9-21-09

Flow out of Mackay Dam is between 300 & 350 cfs. That’s quite a bit higher than normal, but the river still can be waded with caution.  Midges, BWO and terrestrial patterns are the best for top water action.  Small bead head nymphs will bring the best action below.  Look for the lower flows, cooler temps, and shorter days of October to bring improved fishing.


Big Lost River 9-09-09

With flows out of Mackay Dam dropping to just under 400 cfs, cautious wading will get you into action from trico spinner falls, BWOs, midges, and terrestrials.  And the river will offer even better fishing as we move through autumn.   We will keep you current on this improvement.
