Jackson Hole Fly-Fishing Forecast
Welcome to the newly revamped fly fishing forecast for Grand Fishing Adventures. Why a forecast instead of a report you ask? As many anglers come and go into the Teton valleys we thought it would be better serving to give you the angler a forecast of what to expect in terms of hatches, available water that might be opening up, and some local knowledge.
Forecast for July 11st through July 21st: Many locals use the rule of the thumb that when Glory Bowl fully melts out the peak of runoff should have subsided, and when Rendezvous bowl melts out the fishing turns on! Now that Glory is free of snow and Rendezvous bowl almost snow free many anglers are looking forward to the fishing greatly improving. Through the next ten days expect water levels to slowly start to decrease as many tributaries recede from there June runoff peaks. Water clarity will become exceptionally better as we enter the dog days of summer. Currently, the Snake has roughly two-plus feet of visibility.
Load up the boat. It’s time to fish.
The Snake (from GTNP to Alpine):
Plain and simple fishing is improving every day! Bobber fishing in the morning is very productive with afternoon dry fly hatches happening up and down the river. Using a Pat’s rubber legs in size 6 with a prince nymph or copper john variation has been the winning ticket. Many of our guides are switching from standard prince nymphs to a psycho prince variation (tied on a jig head hook and additions of Mylar flash to the body). Top water action has been limited in the slower water but a carefully placed purple chubby Chernobyl has been effective. As water clarity improves so will the fishing. Mayfly’s and Chernobyl’s will be your go to dry flies. If you are wading use caution around river braids as they have yet to settle and the cobblestone can easily let go where you are standing.
The Gros Ventre:
The GV is still a bit out on fishing as the water clarity is less than ideal. Expect the GV to turn around during our next report.
The battle of choosing the right fly.
The Hoback:
The Hoback is an excellent walk and wade river that is routinely overlooked by anglers fishing in and around the Tetons. Currently you can find golden stones and some drakes hatching along the river. As we move into July expect mayfly’s of various sizes. We recommend having purple haze’s and pheasant tail variations ready along with chubby Chernobyl’s in gold and purple. The flows are still higher than normal; however, the clarity is improving daily. Locals note on the Hoback; recent wildfires have left the river drainage prone to washouts. Keep an eye on the forecast if you are headed for a day of exploring up and down the Hoback.
Nothing better than pulling a few of these into the boat.
The Green:
The Green is pumping on all cylinders and will continue to fish well as long as the water coming from the Wind River Mountain Range remains consistent. Keep a keen eye on the weather as overcast days are much more productive then bright blue sunny skies. Drakes and stoneflies will continue to produce. Utilizing the gray drake film critic in a size 14 and golden Chernobyl chubby in size 12 should produce some top water eats. If you are utilizing the wade access points please familiarize yourself with the area of water you will be fishing as the landowners in Sublette County are rather vocal with trespasser’s.
