Big Lost River

The Big Lost below Mackay is turning over as fall air temperatures drop, which will temporarily cloud the water before clarity returns as sediment settles. Morning Trico and Baetis hatches should drive early fishing, though activity will slow once the bugs clear; nymphing produces fish throughout the day. The North Fork has run muddy from recent rain, so focus on the main stem once it clears. There's no need to start at dawn since morning temperatures are chilly, and fishing improves as the day warms. Small mayflies, crane flies, midges, spruce moths, and hoppers round out the mix.
