What to throw right now

Fly anglers
HATCH-MODE FLY SETUP: 5 wt rod with floating line, 9-12 ft tapered leader to 6X fluorocarbon tippet. Match the hatch by stage, emerger (CDC pattern in the film) first, dun (Comparadun, Parachute) second, spinner (rusty spinner) at last light. Cast 3-4 ft above the rise with a reach mend; the line lands sideways and the fly drifts ahead drag-free. Strip-set on small flies, no rod lift.

From a boat or stable bank perch: 6-7 wt sink-tip line, 4-6 ft fluoro tippet to a weighted streamer or beadhead bugger. Cast quartering downstream, mend hard upstream once, then strip-pause-strip through the seam. The fly needs to track in the bottom third of the column; if it skates near the surface during generation you'll get nothing. Drop a split shot 6" above the fly if the sink-tip isn't getting there.
Spinning / casting anglers
HATCH-MODE SPIN SETUP: ultralight 6'-6'6" rod, 4 lb fluoro all the way through. Two productive rigs: (1) #00 or #0 Mepps Aglia or Joe's Fly in olive-and-yellow, cast quartering upstream + retrieve just fast enough to spin the blade through the seam; (2) a #16 beadhead Pheasant Tail OR Zebra Midge tied to a 24" tippet hanging below a 1/2" pencil bobber, drifted dead-naturally through the same lane a fly angler would target. The bobber rig outfishes the spinner once trout are keyed on a specific bug.

Medium-action spinning rod, 8-10 lb braid + 6 lb fluoro leader. Use the heaviest jighead that still lets the lure breathe (1/4 oz minimum during generation; 3/8 oz if the flow is heavy). Cast across-current and slow-roll back with the rod tip down. Fish the slack-water pockets behind boulders + dam piers; trout stack there during high flow waiting for food.
