Recent rainfall and cooler daytime temperatures have provided some relief from high water temperatures and improved flows throughout southeastern Wyoming. The North Platte and Laramie Rivers are still getting a little on the warm side in the afternoons, however higher elevation tributary streams have cooled off nicely and are fishing well.
It is important to keep an eye on water temperatures and to carry a stream thermometer at this time of year to avoid over stressing fish. Water temperatures are cooling off a bit, but we are still in the dog days of summer and anglers should be persistent in checking water temperatures, particularly in the afternoons.
Upper North Platte
Flows: ~ 150 cfs
Conditions: Fishing conditions have been gradually improving on the Platte, and recent rainfall and cooler daytime temperatures have cooled things off a bit. Afternoons are still getting warm, so be sure to keep an eye on water temperatures as midday approaches. The best window for fishing will be from first light until about midday. Tricos are the primary hatch right now, and fish should be keyed in on these tiny bugs. A spinner pattern with an emerger/nymph trailer can be quite effective throughout the morning.
Flies: Dry flies; Chubby Trico Spinner, Parachute Adams, Chubby Chernobyl, Swisher's Foam PMX, Amy's Ant, 409 Yeager, B/C Dropper Hopper, Stimulator, Elk Hair Caddis, Light Cahill, Little Yellow Stone,
Nymphs; RS2, WD40, Rubber Legs, 20 Incher, Hare's Ear, Prince Nymph, Pheasant Tail, Copper John, Dirty Bird, Devil Jig, HDA FAV Variant, Blow Torch, Duracell Bomb
Flows: ~50 cfs
Conditions: The Laramie River jumped up quite a bit over the weekend, and is now dropping in flows and settling back down. Fishing should be a little more productive over the next week as a result of this.
Flies: Little Yellow Sally, Light Cahill, Parachute Adams, Stimulator, Elk Hair Caddis, Griffith's Gnat, Copper John, Pheasant Tail, Hare's Ear, Prince Nymph
Flows: 30 - 75 cfs
Conditions: Higher elevation North Platte tributary streams remain one of the better options for fishing right now. Cooler daytime temperatures and recent rainfall should provide a longer fishing window than the Platte and Laramie River can offer at this time.
Flies: Stimulator, Elk Hair Caddis, Light Cahill, Parachute Adams, Amy's Ant, Dave's Beetle, Copper John, Pheasant Tail, Hare's Ear, Prince Nymph
Alpine Lakes and Streams
Conditions: Alpine lakes and streams should provide anglers with a great option with the recent rising temperatures. Water temperatures will remain cooler at higher elevations and fish will continue to feed aggressively as they take advantage of the short growing season. Alpine lakes and streams can provide a great option for some surface action with attractor dries. Ants, beetles, small hoppers, and caddis patterns are good dry fly imitations to start prospecting with.
Flies: Amy's Ant, Dave's Beetle, CDC Ant, Hippie Stomper, 409 Yeager, Hare's Ear, Prince Nymph, Copper John, Wolly Bugger, Pine Squirrel, Platte River Spider
