From the benchWith water temps at 67.6°F, fish are going to be stressed during peak afternoon heat — focus your dry fly and nymph game hard from first light until about 10 AM, then shift to shaded deep pools with a sculpin or stonefly nymph bounced along the bottom. The real money window is the evening caddis hatch starting around 6 PM; position yourself in the tailouts and slower runs 30 minutes before the hatch kicks off and let the fish come to the surface before you start casting. Use a 5X tippet minimum for the smaller dries and keep your net in the water to minimize handling time on warm-water days like this.
