Hot’s got nothing to do with water temperature. Thankfully, the Farmington is running cool even thought they’ve dropped the level (currently about 170cfs in the Permanent TMA). No, I’m talking about the bubbling, boiling (figuratively), riffly whitewater sections of the Farmington. That water is is oxygenated and loaded with food. It’s also studded with small pockets and micro boulders — places trout like to hang out. If it’s at least a foot deep, it’s fair game, and you might be surprised to discover what’s living there. Swing wets, drift nymphs (no indicator), hopper/dropper — all of those are good choices for covering the hot water. Oh. And hold on. The chance of a big fish is always there.
This is what I’m talking about. The angler is one of my clients from a few years ago. On this day the water was far lower than it is today — I think the flow was only double digits, and the riffle was barely a foot deep. Normally you’d shoot past it without another look. But on this day we banged up trout after trout. Note the method: tight line nymphing. Indicators aren’t necessary here because of the water depth; plus, you’ll feel the strike or see your sighter lag a bit. That’s when you set hard downstream. Please use the strongest tippet you can, and get those fish in fast.
