REPORT AS OF 8/23/2017
Hot weather looking to make its return to the area. There will be quite the warming trend for the following week with above average temperatures for the month. Bridgeport Reservoir is now open and anglers can launch their boats from the marina ramp again. East Walker river at perfect flows now. Big fish are on the chew along with some smaller rainbows. June Lake area waters still fishing well from a float tube or boat with sinking lines and various streamer patterns. Rush Creek good for nymphing and dry dropper fishing with a light weight rod. San Joaquin River still dropping and fishing good with dry flies. The Mammoth Lakes have been good by float tube with sink tip and full sink lines. Dry fly fishing good in the afternoon and evenings. Upper Owens River good as fish are rising for dry flies drifted along the undercut banks. Hot Creek clear and decent with a dry dropper rig. Crowley Lake still kicking out nice big fish. Shallow water fishing has been good along the weeds and channels. Middle Owens up at 500 cfs. Running quite high for fishing from the banks. Wild Trout section still high for wading. PVR good with full sink lines from a float tube while pulling streamers. Gorge getting some water in it again.
Fishing has been very consistent here for large quality fish. Other internet reports are apparently experiencing slower fishing. We have been netting large fish daily with plenty of takes in shallow water. The fish are in the weeds and filling themselves with damselfly nymphs, callibaetis, and perch fry.
Fishing closer to the channel has yielded great results and the afternoon wind has really been stirring up the bigs to bite. This is a great time to fish the shallows, as the crowds are very light now and the weather is pleasant. The wind does not negatively affect the bite when fishing with perch fry imitations as it sometimes can with midges, so the fish continue to bite all day long. Many fish have been in the channel in McGee early in the morning, then making their way onto the flats as the sun gets higher and the breeze picks up. North Arm, McGee Bay, the Hiltons, and Crooked Creek have been excellent spots. Our Parallel Assassins Light and Parallel Punk Perch in dark and light have been perfect imitations for fooling these fish.
San Joaquin River
Flows dropping here daily. Currently at 90 cfs. Excellent water conditions with fish taking most dry flies in the right size presented properly. Fishing has been good from the campgrounds down and upstream. Stimulators, Caddis, Mayflies, and small hoppers have been great flies for the area on a 3-weight rod.
River now at an excellent flow rate at 68 cfs. Water is crystal clear above the Hot Creek confluence and the further up you travel. Fish are readily taking dry flies and droppers in the clear water above the bridge. The fish are scattered along the river in this section and you may have to do a bit of run and gun fishing. 3 or 4 weight rods are a great set up for these fish. They are very aggressive when taking a dry fly presented to them properly. Mosquitoes are still around in good numbers so juicing the skin up with bug spray wouldn't hurt.
The section upstream from the Benton Bridge is open year around with special regulations. Seasonal closures, and angling restrictions apply downstream from the bridge, check regulations before fishing in this section.
Middle Owens River/PVR/Wild Trout section (Bishop Area):
500 cfs on the river currently with 175 cfs coming through from Bishop Creek. River has come up this past week making the water off color. The reservoir is fishing good while pulling full sink and sink tip lines from a tube. Go with dark streamer colors on the overcast thunderstorm days and lighter colors when the sun is high in the sky and bright. Wild Trout area is high right now and it is probably best to fish elsewhere.
This fishery remains open year around. Special regs from the footbridge at Pleasant Valley campground to the fishing monument 4.7 miles downstream.
Flows now at 41 cfs. Water looking really good now. Try dry fly and dropper combos along the far edges of the banks. Fish are eager to jump on whatever offering falls from the banks.
This is a year around fishery with special regs in place.
East Walker River:
River now at 340 cfs. Near perfect flows at this release and great fishing in all areas of the river. Major trico hatch in the mornings. Lots of pressure in the "Miracle Mile" section, but lots of open water downstream. Good quality rainbows and browns showing up and biting on heavily weighted nymph rigs. San Juan worms, Parallel Punk Perch, midges, PT's, and Copper John's are all good flies right now.
This fishery is open year around below the Bridgeport Reservoir dam to Nevada State line. Open year around in Nevada also.
We want to wish the new management for the Bridgeport Marina and RV Park the very best of luck, & many solid snow packs. The facility is back and operating with good reports from tubers and boaters fishing the Buckeye Bay section.
