All of our waters are in great condition. Flows and clarity are perfect on big rivers and mountain brooks. Temperatures have been on the rise. We’ve had a week of very warm and humid weather with regular bouts of rain. The warmest temps will be on the big rivers that get pounded by the sun.
We avoid fishing for trout in waters that reach 70 degrees, due to the stress that trout are subjected to in those temps. If you are a catch and release fisher, It’s time to get out the thermometer to be sure you’re fishing for trout under 70.
Luckily we have plenty of other options in Vermont. Lately, due to it actually being too hot for anglers to stand in the sun, so we have been heading to the mountains for some excellent brook tout fishing. Mountain brooks stay cool all the time and we have plenty to explore. 
This time of year, brook trout feed aggressively on the surface. We throw a lot of hoppers and large wulff style flies. Brook trout fishing involves a hike up a cool mountain steam, wet wading in some of the most beautiful places in Vermont, so plan on some exercise. You’ll be casting in tight vegetation and overhanging canopy to place a fly in pools as small as a bathtub. 
Gear is simple. A short full flex rod that roll casts well. High floating flies like wulff style flies and hoppers. Short leaders with lite tippet. Polarized sunglasses, water and bug spray. That’s it.
