Mammoth Lakes Area

Weather Report

Don't forget your water bottles and sunscreen as you hit the lakes, rivers and creeks. The water's reflection seems to like to help the sun in its constant attempts to turn us all bright red and leave us sadly remembering the trip. Don't forget life jackets for the kids if you are fishing from a boat!

REPORT AS OF 8/2/2019

Summer is in full swing - flows are good, water clarity is good, hopper fishing has been going off!

We only report first-hand info from our guides on the water daily, Bishop to Bridgeport.

Mammoth Lakes Basin

Water Conditions: Good

Fishing Conditions and Hatches: Good

Stripping streamers and scuds is still productive. Also fishing dry dropper rigs will work this time of year. Most fish will be caught off the nymph, however, you may get a few takes on the surface. Callibaetis and Damsels are now emerging mid to late morning especially on Twin Lakes, the Callibaetis Spinner fall coincides with the emergence so just another piece of the puzzle to figure out. With the new hatches start concentrating along the weed lines and drop offs. Early and late fish midge dries in and around the weed beds. UPDATE: Lake Mary now has big Damsel hatches as well, late morning until early afternoon. If you're in a boat or float tube cast out towards the drop offs and fish back towards shore or any weed beds or logs where the Damsels can crawl out to emerge. Shore fishing is a little trickier but any place you can cast out into the lake is worth trying.

Fishing inflated worms about 2 feet off the bottom has also been productive. Garlic pinched nightcrawlers and pink mousetails have also been effective.

STREAMERS: Docs Twin Lakes Special, Brown, Olive, & Black #10-12

Guide's Hint:

Hot Creek

Water Conditions: Good

Flows are at 50cfs as of 8/1

Fishing Conditions and Hatches: Good

Flows continue to drop at Hot Creek. The weeds are still not a factor, and Hoppers are everywhere. Most fish are looking up and want a fly sitting high off the surface. If you are getting refusals, treat your fly, or go down a size. Tricos and Caddis start the day with a smattering of PMDs and small Stoneflies mid-day. The PMDs and Stoneflies are starting to fade but still keep an eye out for them. Evenings are Midges and male Tricos with plenty of Caddis if the wind dies down.

Recommended Flies:

DRIES: Parachute Extended Body BWO #16-18 | Chernobyl Hopper #14-12 | Spent Partridge Caddis #16-18 | Stimulators #16-18

NYMPHS: Hares Pheasant #14-18 | Barr's Uncased Caddis #14-20 | Juju Baetis #16-20 | Zebra Midge #18-22 | Mercer's Micro Stone #16-18

Guide's Hint:

San Joaquin River

Water Conditions: Poor to Fair

Flows are at 198cfs as of 8/1

Fishing Conditions and Hatches: Unknown

The road to San Joaquin has recently opened. Flows are getting lower, and I am starting to hear reports of improvement but nothing specific. If you decide to head down there I recommend the afternoon. We will start to see better conditions when flows drop. Still not getting much information but if you're going to fish it the afternoons and evenings would be a better bet. The Drakes should be coming off soon in the evenings, anytime you get to use #12 dryflies is a treat.

Recommended Flies:

Stimulators #14-18 | Flavilinea Dun #12-16

NYMPHS: Hares Ears #14-18 | Red Copper John #14-18

Guide's Hint:

Crowley Lake

Water Conditions: Good

Fishing Conditions and Hatches: Good

Fishing is about as good as it gets on Crowley, the only downside, as is common in July, the best fishing is localized in McGee Bay. Deep water midging will be most productive outside the weed beds in McGee Bay. Look for fish in 20 feet of water or more. Hilton had about a week of stardom but has slowed considerably. The damsel and callibaetis emergence has picked up and the perch fry are now eating size, several anglers have caught large fish that have coughed up 20-30 perch fry at a time. There are fish showing inconsistently all around the lake so with a little exploring you might find the next hot spot and have it to yourself for a while.

Recommended Flies:

DRIES:

NYMPHS: Copper Zebra #16-18 | Shaft Emerger #16-18 | Albino Baron #16-18 | Bubba's Callibaetis #14-16 | Damsel Flies #12-16

STREAMERS: Marabou Leech Brown #12 | Crystal Bugger Olive #12 | Punk Perch #14-16 | Balanced Birds Nest #14-16

Guide's Hint: If you've been consistently catching fish but somewhere around 10-11 things slow down try putting a callibaetis nymph on.

Upper Owens River

Water Conditions: Good

Flows are at 76 cfs as of 8/1

Fishing Conditions and Hatches: Good

Fishing has gotten a little tougher on the Upper Owens. The larger fish coming out of Crowley are spreading out and with all the fishing pressure they're getting a lot more selective. Tricos are hatching at first light with the spinner fall mid morning, PMD mayflies are hatching around noon, and the Caddis and male Tricos are out in the evenings. Hopper action is best when the wind blows. Fishing seems to shut down in the late afternoon, but picks up again around sunset.

Recommended Flies:

DRIES: Stimulator #16-18 | Elk Hair Caddis #14-18 | Extended Body BWO #14-18 | CDC Spring Hopper Tan or Yellow #10-16 | Rubber Leg Parachute Hopper #10-16 | Brooks Sprout Trico #18-22

NYMPHS: Hares Ear #14-18 | Radiation Baetis #16-18 | Barr's Uncased Caddis #14-16 | Zebra Midge #16-18 | WD-40 black #18-20

STREAMERS: Shock Collar Leech #10 | Woolly Bugger, Olive & Brown #12-10

Guide's Hint:

Lower Owens River

Water Conditions: Fair

Flows are at 401 cfs as of 8/1

Fishing Conditions and Hatches: Fair-Good

Flows are still a little high, but if you can stand the heat and high flows you should have plenty of privacy. Most fish will be caught nymphing. There is some surface action in late mornings. Keep an eye out for Stonefly and Mayfly hatches around noon. Sort of a broken record but click on any stream report right now and you'll know what's happening here. Micro Caddis emergence starts at daybreak followed immediately by the female Tricos and then around 9 the spinner fall commences.

Recommended Flies:

DRIES: Para Adams #14-16 | Spent Partridge Caddis #16-18 | Yellow and Tan Stimulators #14-16 | Brooks Hot Creek Caddis #20-24 | Emerging Female Trico #20-22

NYMPH: Pheasant Tail #14-18 | Tungsten Psycho #16-18 | Barr's Trico Emerger Black #20-22

STREAMERS: Wooly Bugger Olive & Black #10-12 | Mini Sculpin Olive & Black #10-12

Guide's Hint:

East Walker River

Water Conditions: Fair

Flows are at 324 cfs as of 8/1

Fishing Conditions and Hatches: Fair to Good

Water temperatures are low to mid 60's in the mornings and mid to high 60's by early afternoon when the fishing tends to slow down. The early morning Trico emergence and following spinner fall is impressive along with the enormous (#12-14 2xl) orange and yellow midges flushing out of the reservoir. Caddis are active all day long with a midday PMD emergence that the fish seem to be ignoring.

Recommended Flies:

DRIES: Spent Partridge Caddis #14-16 | Panty Dropper Hopper #10-14

NYMPHS: Tungsten Psycho #16-14 | Golden Bead Biot Epoxy Stone #8-10 | Dead Drift Crayfish #8 |BH Chiron Larva Blood #14 | Worm-Annalid #16-18

STREAMERS: Meat Whistle | Sculpzilla
