Big Lost River

Big Lost River 8-19-15

Flow out of Mackay Dam had been pretty constant at around 340 cfs ( very near its mean flow for this time of year) for the last several days. This AM, however, it was upped to about 430 cfs. That’s a pretty good jump for this small river, so wade carefully. Any day now tricos will be the major emergence, so be ready to try the river during the AM hours.


Big Lost River 5-2-15

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 8-2-14

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.
