Big Lost River

The days of easy wading in the Big Lost River below Mackay Dam are over for a while. Early yesterday flow out of the dam was raised from just under 100 cfs to 573 cfs.  Now the best way to fish here is to float through. We’ll keep up on when the river returns to a flow safer for wading.

Flow out of Mackay Dam remains at just under 100 cfs.  Could increase any day now when irrigation demands kick in and put an end to great midge and BWO activity with fish responding.

Big Lost River, Fishing Reports

Flow out of Mackay Dam has dropped from a little over 200 cfs to 160 cfs in the last few days. This means easier wading, warmer afternoon water temperatures, less overhead cover, and therefore a greater need for being stealthy and for playing fish quickly.   Some western green drakes remain here, but terrestrial patterns are becoming more effective.  Tricos are yet to be important, but should begin to be such any day now.

Flow out of Mackay Dam  is currently about 185 cfs and has been just below 200 cfs for several days now. This is a great flow for not only good wading conditions in the river below, but also enough to provide good cover for trout residing there.  Look for PMDs, afternoon flavs, and evening caddis activity to attract trout into a feeding mode. So bring life cycle patterns for all of these, plus traditional dry and wet attractors.

On May 15th the flow out of Mackay Dam increased from 90 cfs to 500 cfs!  That increase put the “kibash” on easy wading in the river below.  It will also make for tough fishing.

Flow out of Mackay Dam is about 80 cfs. This means wading in the river below is easy. Midge and some BWO emergences still attract fish here, but flows are sure to increase when irrigation demands kick in. We will report here when this increase takes place.

With flow less than 100 cfs below Mackay Dam, fish are concentrated and taking midge life cycle patterns with gusto.  Any day BWOs will begin emerging in significant numbers giving feeding trout afternoon variety. Pick low light conditions for best fishing.   With such low flows expect fish to be wary making a stealthy approach necessary.

Flow out of Mackay Dam is only 54 cfs. This amount will concentrate fish into deeper holes and result in little bank side habitat for young trout.  Small bead head nymphs, BWO and midge life cycle patterns will bring action. Be ready for stormy weather if you try the river here!

With flow out of Mackay Dam down to 170 cfs, wading the river below is easy. Just remember that a lot of private land borders the river here. You are legal by walking within the high water mark, so respect the private land and enjoy tricos in the morning and BWOs later in the day. Look for the river below the dam to drop further as the water storage season begins.
