From the benchWith water at 42.8°F, trout metabolism is slow — get your nymphs all the way to the bottom and slow your drift down. Focus on the deepest seams and undercut banks in the 2-4 foot depth range, using a tight-line or indicator setup with enough weight to tick the bottom. The best action will come during the midday warming window between 11 AM and 2 PM when BWOs and midges are most likely to pop. Rain is moving in through the day and mixed precip tonight, so if you're planning a full day, fish hard this morning and be prepared for rising, slightly off-color water by late afternoon.
