FISHABLE
Grey Reef at 501 CFS, Miracle Mile at 630 CFS. Unseasonably mild winter has kept edge ice minimal. Water temps 39-41°F with 2-3 ft visibility. Nymphing and streamers producing well.North Platte River
Current Hatch Activity
Olive and black midges hatching reliably. Nymph rigs with large attractor flies (annelids, worm patterns) trailing smaller Juju Baetis (#18-20), RS2s (#20-22), or Mayhem patterns producing best. Streamer bite strong in certain locations—dungeon patterns and slow-stripped leeches/crayfish effective. At Miracle Mile, scuds and leeches as top droppers with midge trailers. Trout Spey anglers finding success with Colonel Kurts and Platte River Spiders.

Unusually mild winter has kept Grey Reef wide open with minimal edge ice—rare for February. Flows stable at 501 CFS. Miracle Mile running 630 CFS with good access. North Platte Lodge opening two weeks early (Feb 16) due to favorable conditions. Night flushing flows still occur but normalize by mid-morning.

spring
March through May sees flows begin to increase. Midges and BWOs dominate. Streamer fishing becomes effective as water warms. Watch for flow changes as dam operations shift.
summer
Flows increase to 2,000-3,000 CFS. PMDs, caddis, and terrestrials produce well. Float fishing becomes primary method. Early morning before crowds is best.
fall
September through November is excellent. Browns get aggressive. Streamers produce trophy fish. Flows begin to decrease toward winter levels.
