The Lower North Platte at Grey Reef

Grey Reef has developed into the finest tailwater trout fishery in the lower 48 states.  The Reef is located below the fourth impoundment of the series just south of Casper, near the small settlement of Alcova, Wyoming.  Grey Reef is primarily a float (driftboat) fishery with large agricultural ranches lining both banks.  There are public access sites mainly located at the boat ramps allowing the wade angler some opportunity to these huge trout.  Fishable almost year round, Grey Reef holds rainbow and brown trout with trophy size behemoths in the 10-12 pound range.  Consistency is the rule on Grey Reef with warmer spring flows and cooler late summer flows along with predictable hatches and catch rates. 

Nymphing is the norm using PT's, copper john's, san juan worms, and scuds below the base of runs and riffles.  Large flat water sections offer the dry fly fisher the occasional take, mainly terrestrials and blue wing olives in late summer, but casting large streamers to the banks can be the most rewarding with violent strikes from giant predators.


Large 6-7 weight fly rods are recommended to fight not only the large trout but also the winds that occur in the afternoons.  Grey Reef is popular and experiences quite a bit of pressure but early spring before runoff during the rainbow spawn and late summer and early fall during the brown spawning period is quite productive with fewer crowds leaving the rest of the summer for those freestones.
