Big Lost River

The Big Lost will run low and clear through early September, making the river highly accessible but requiring careful stealth and deliberate movement. Deeper greenish runs and edges will hold the best fish, particularly in the morning when cooler temperatures extend the productive window. Expect Tricos and Baetis in midmorning, along with small mayflies, caddis, hoppers, flying ants, and craneflies. Afternoon fishing slows dramatically, so plan accordingly and keep your fly selection mobile to match what's happening on the water.
