Big Lost River, June 22nd, 2021

Flow out of Mackay Dam is a bit above 300 cfs. Wading with caution here can be done. Try streamer and caddis and PMD life cycle patterns. It is likely that the reservoir above will undergo significant draw-down to satisfy downstream irrigation demands. That means flows in the river below could remain at this level for weeks to come. Also expect fly fishing company from the Ketchum-Sun Valley area because of less than good current fishing conditions in the Big Wood River system. This will be particularly the case along the river above Mackay Reservoir and in Copper Basin.
