I would go for a rescheduled October time, second or third week. Frustrating, but hey, we're still on the right side of the dirt.
I do have a plan "B" for the same dates, if Salt Creek stays no-go, the I will go to a closer to home spectacular reservoir of great size of both water and fish. Flaming Gorge. They have four pound Kokes in there, at least five kinds of big trout and char including Lakers that get to over 40 pounds. Also tons of Smallmouth Bass., as well as a butt-fugly slimy eel looking fresh water cod called a Burbot, AKA poor man's lobster. The presentation diversities driven by the species variation demand keen attention to numerous, diverse details. It's like getting to ski at a world class resort like Jackson Hole, Park City/Canyons or Mammoth Mountain. And just like the Canyons sits huge unique in it's on mountain character right next door to it's sister resort Park City, the Green River tailwater fly fishery below the flaming Gorge dam offers 20+ miles of beyond blue ribbon carefully managed trout water, I've float tubed, caught, and seen some of the most gorgeous browns in my life there in the "A" section. I know a couple fantastic full time fly fishing guides that work there if anyone wants to give the Green a go. It's prime rowboat dory water, nimble two seaters easier to operate there. Fishing the lower Green with a guide when the fish are "on" is like is like skiing Alta on a snowing day with one of their ski instructors to show you where the goods are stashed. And right next door is the completely different feeling 95 mile long Flaming Gorge Reservoir where my Allison is going to roam like a Mustang on wild oats...
Swim Beach is the most likely sleep spot of several favorites where I will be car camping in a 4 season hardcore weather type of tent or a tent cot if the weather is less energetic. There are no improvements there. It's not a campground, but camping is permitted there. It's full on hardcore camping or RV-ing at a roomy spot. The wind can get pretty spectacular at that location, like many places in Wyoming. Having a self contained RV is even better than what I have. A mile-mile and a half away the Lucerne marina store, boat ramp, and dock/slip/rental/gas facilities. My boat will be sitting in a powered slip, so can either drive over from the camp site or ride a mountain bike to and from the boat dock. Personal goal is jigging a 20 pound Mackinaw. There are a couple fave boat-in spots for a more hardcore experience well worth the extra effort of setup and breakdown. The local coyotes enjoy singing opera at the nightly sun sets, pretty cool spot to hang out. Feel free to join if you are in the area.
But frankly, I'd rather do the original plan...
