Lower Owens River Fly Fishing Report – Bishop CA – 3.30.26

March 30, 2026
, , , , , , Fishing Reports

Fishing on the Lower Owens River is starting to feel a lot like early spring. Flows have come up recently and are now hovering around 280 CFS, adding some push to the river but still leaving it in very fishable shape. Even with the bump in water, the river is running fairly clear, as 280 CFS is still well under half of the river’s flood-threshold potential, so visibility has remained good. The added current has shifted many trout into softer edges, seams, and slower pockets where they can get out of the heavier flow. Fish are holding along undercut banks, deeper riffles, and inside bends where they can feed comfortably while conserving energy.
The main hatch right now continues to be the Baetis hatch, with activity typically building from late morning into the early afternoon, especially on cooler or overcast days. When fish are looking up, small BWO dries in the #16–18 range can bring some quality trout to the surface. Outside of the hatch window, nymphing has been the most consistent approach. Baetis nymphs, Pheasant Tails, and Hare’s Ears in the #16–18 range have all been producing when fished deep through seams, drop-offs, and softer transition water. A few early caddis hatches are also beginning to show, so keeping a couple caddis pupae in the rotation can pay off.
With California’s snowpack sitting around 20% of normal, it’s unlikely the river will push dramatically higher or sustain elevated flows for a long period this spring. At the moment the river is still very manageable to wade with some caution, and if flows stabilize around this range while temperatures continue to warm, the Lower Owens should keep producing steady Baetis activity and solid midday dry fly opportunities in the coming weeks. 🎣

Lower Owens River Winter Fishing Update

The Lower Owens River outside Bishop continues to fish exceptionally well this winter, with flows holding steady at 100 cubic feet per second and a return to unseasonably warm daytime temperatures making for some of the most comfortable winter fishing conditions of the season. The river remains wide open, highly wadable, and in excellent shape.

Clear, cold water combined with stable releases has trout well distributed throughout the system. Fish are set up in soft edges, shallow riffles, tailouts, and structure that was too fast or too deep earlier in the year. With flows at 100 cfs, anglers can comfortably access water that’s often difficult to reach during higher seasonal releases.

Nymphing continues to be the most consistent approach, with both indicator rigs and tight-line techniques producing steadily throughout the day. Covering water and focusing on softer seams and transitional water has been key to finding fish.

We’re also seeing consistent BWO (blue-winged olive) hatches as well as caddis beginning around noon Depending on where you are positioned on a particular bend or stretch of river, the hatch can last anywhere from 15 minutes to well over an hour. As bugs come off, look for rising fish in foam lanes, back-eddies, and softer seams typical of classic Lower Owens water. Calm conditions paired with the warm temperatures are helping extend the hatch window and improve dry-fly opportunities.

With light winter pressure, steady 100 cfs flows, dependable midday BWO and Caddis activity, and unseasonably warm weather back in the forecast, this remains one of the most rewarding times of year to explore the Lower Owens. Hungry trout, excellent access, and multiple productive techniques make this a prime winter fishing window.

Upper Owens River Fishing Report : Mammoth Lakes, CA – 11.30.25

November 30, 2025
, , , , , Fishing Reports

Winter temperatures have settled into the Upper Owens, and conditions have up for a classic big-fish season. The early snowfall has long since melted off, leaving the Long Valley meadow dry and wide open while cold nights should continue to push more lake-run trout into the system. With the river flowing at an average of 100 cubic feet a second the annual Crowley Lake trophy run is pretty mcuh fully underway, with fresh fish showing throughout the river.

Pressure has been day-to-day—some mornings you’ll find long stretches of river almost to yourself, while other days the fish barely get a break from a hook drifting past them. Regardless, the quality of the trout in the system makes every session worthwhile.

Daytime highs are hovering around 50 degrees, but don’t let that fool you—mornings remain well below freezing, keeping the water cold, clear, and perfect for sight-fishing. Visibility is great both above and below the Hot Creek confluence, but that clarity combined with pressure means fish are on high alert. Stealth continues to be one of the biggest keys to success: slow movements, low profiles, and precise presentations.

Fishing Overview

Lake-run rainbows and a few browns are holding in the classic winter structure—deep bends, undercut banks, soft dark edges, and any bucket that offers depth plus cover. Fresh fish are filtering in steadily, and the consistent cold has them settling into the river in decent numbers.

Low-light windows remain best for approaching the biggest trout in the skinniest water, while midday sun creates difficult conditions.

What’s Working Now

Nymphs & Streamers:
Pheasant Tail variations, Perdigons, midges, Soft Hackles (#12–18), San Juan Worms, and attractor nymphs like Lightning Bugs.
Streamers cand draw big reactions, especially when fished slowly and deliberately.

Techniques:
Indicator and tight-line nymphing are producing steadily. Euro-style rigs and classic indicator style nymphing excel in the low, clear flows. Streamers can be a reliable option when fish refuse smaller patterns.

Surface Action:
Minimal, but occasional BWOs and small caddis show throughout the day. Expect mostly smaller residents responding on top.

With the big-fish migration in full swing, cold clear water, and fluctuating angler pressure, this is prime time to fish the Upper Owens. Conditions will only improve as winter deepens.

Lower Owens Fly Fishing Report : Bishop, CA – 11.29.25

November 29, 2025
, , , , , , , , , , , Fishing Reports

The Lower Owens River outside Bishop, CA has shifted fully into its late-fall mode, with flows continuing to drop and now settling around 90 cubic feet per second. This is classic low-water season on the LO — the river is wide open, extremely wadable, and offering access to water that’s been unreachable for most of the year. With clear, cold flows and steady insect activity, the fishing has been nothing short of excellent.

Wild trout are spreading out across the system, taking advantage of softer edges, shallow riffles, and structure that was too fast or too deep earlier in the season. While nymphing remains the most consistent method — both indicator and tight-line setups are producing all day — anglers are now seeing the first reliable windows of dry-fly action, especially during calm mid-mornings when blue-winged olives begin to trickle off. Expect rising fish in softer seams, back-eddies, and the classic Lower Owens foam lanes.

With crisp late-fall air, and the river in prime shape for exploration, this is one of the most rewarding periods of the year to fish the LO. The combination of light pressure, hungry trout, and a variety of effective techniques makes this an ideal time to get out and cover water.

Upper Owens River Fishing Report – Mid October

It’s starting to feel like fall for real on the Upper Owens, and everything is lining up for a stellar season. Flows have bumped up to 99 CFS, adding depth and energy to the river, and the first snowfall of the season dropped about 6 inches across the Long Valley meadow. While most of it will melt off in the coming days, it’s a sign that winter is knocking—and with it, the highly anticipated run of Crowley Lake’s trophy trout.

The water is running clear both above and below the Hot Creek confluence, offering excellent visibility—but that also means the fish are on high alert. In these conditions, a stealthy approach is critical. Anglers need to move slowly, keep a low profile, and make precise casts to avoid spooking both resident trout and early-arriving migratory fish. The payoff is worth it—these are prime sight-fishing conditions that reward patience and finesse.

Fishing Overview
Resident and migratory rainbows and a few browns are active and holding in deeper pools, undercut banks, and along soft dark edges—especially in lower light parts of the day. While the first wave of lake-run fish is trickling in we can see them settling into any deep and dark area the river offers. It’s a possible slow start compared to stronger years, but the rise in flows and cold weather could trigger additional movement.

What’s Working Now

  • Nymphs and Streamers: Pheasant Tails variations, San Juan Worms, midges, Soft Hackles (#12–18) Peridons, lightning bugs, ect. Attractor nymphs of any kind are worth trying.
  • Techniques: Indicator nymphing and tight-line nymphing are the most consistent producers. Streamers? Always
  • Surface action: Sporadic, but small Blue-Winged Olives and caddis are starting to show throughout the day with only small fish responding

With clear water and light pressure, now is the perfect time to plan your next fishing trip to the Eastern Sierra to experience the Owens River system. Both the Lower and Upper Owens are premier fly fishing destinations during the winter.

Lower Owens River Fishing Report : Bishop, CA – 9.22.25

September 22, 2025
, , , Fishing Reports

The Lower Owens River, just outside Bishop, CA, has entered a classic early fall transition, with flows dropping significantly over the past week to around 180 cubic feet per second. This shift has opened up the river in a big way, creating highly wadable conditions and access to prime water that’s been out of reach for much of the summer. The cooler, clearer water has wild trout active and spreading into new lies, while the first signs of fall—crisp mornings, golden cottonwoods, and changing leaf colors—set the scene for some of the most scenic and productive fishing of the year. Anglers are now able to cover much more water on foot, with excellent opportunities using classic nymphing setups as well as tight-line nymphing throughout the day. Fish that spent summer in deeper slots and slower seams are now redistributing across riffles, pockets, and softer edges, offering fresh chances at quality wild trout. With low pressure, beautiful weather, and the river in ideal shape for exploration, this is the window many have been waiting for.

The Upper Owens River is entering a transitional phase as late September sets in, with flows holding steady around 65 cubic feet per second and the river winding through golden meadows under crisp morning skies. Water clarity remains best above the Hot Creek confluence, offering great sight-fishing opportunities, while the water below is more stained but still productive for anglers using flashier patterns and a stealthy approach. Resident fish are holding in undercut banks, deeper pools, and riffles, especially during the early morning and evening hours. Subsurface flies like midges, Pheasant Tails, San Juan Worms, Soft Hackles, and Parachute Adams in sizes #12–18 continue to be effective, with dry-dropper setups and tight-line nymphing producing the most consistent results. Surface action is still slowly picking up during low-light periods with Blue-Winged Olives and caddis beginning to appear. Most notably, anticipation is high as the first signs of Crowley Lake’s migratory rainbows and browns have started to show, with a few early arrivals moving into the system. These trophy fish will continue to push upstream in greater numbers with each passing cold front, marking the beginning of one of the most exciting times of year for Eastern Sierra fly fishing. Now is an ideal time to scout water, fine-tune your approach, and enjoy the last quiet days on the river before the fall run kicks into full gear.

Lower Owens River Fishing Report : Bishop CA – 9.1.25

August 31, 2025
, , , Fishing Reports

The Lower Owens River, just outside Bishop, CA, has delivered consistent and exciting fly fishing opportunities throughout the summer for those who know the river at these levels. Flows have held steady around 450 cubic feet per second, creating a dynamic and healthy river system. These elevated flows have kept the water cool and clear, ideal conditions for wild trout to remain active and well-distributed across the system. The higher volume has also limited access in certain areas, which has helped reduce pressure and give larger fish a chance to settle into prime holding water.

In the coming weeks, flows are expected to begin dropping, which will open up access to sections of the river that have been difficult to fish during peak runoff. As this happens, anglers will start to encounter water that hasn’t seen much pressure all summer—and with that, the opportunity to connect with some of the river’s larger, more elusive trout. Fish that have been holding in deeper slots and soft seams will begin to slide into new lies, offering fresh opportunities for both nymphing and dry-dropper setups throughout the day.

Wading access will become significantly easier as the water drops, giving anglers on foot much more room to explore. With healthy water conditions, a robust wild trout population, and fish beginning to redistribute as flows recede, this is shaping up to be one of the most rewarding fishing windows of the season.

We’ll continue to monitor conditions closely as fall approaches. For those looking to explore the Lower Owens while the river transitions and reveals some of its best water, now is the time to plan a trip.

The Upper Owens River continues to flow steadily at around 80 cubic feet per second, this fly fishing legend continues winding through a beautiful, open valley just below the town of Mammoth Lakes. With summer settling in, the meadows are green, insect activity is increasing, and water clarity remains good—ideal conditions for those looking to enjoy some peaceful, scenic fly fishing. While the major push of trophy rainbow and cutthroat trout has tapered off since the peak of the spring migration, there are still opportunities to connect with a few of these larger holdovers. Anglers willing to hike and put in the time may find success targeting deeper pools, undercut banks, and faster riffles where these big fish tend to hold as the days warm up.

Fishing remains productive with a balanced mix of attractor patterns and more realistic imitations. Subsurface offerings like midges, San Juan Worms, Pheasant Tails, Soft Hackles, and Parachute Adams in sizes #12–18 are working well. For those looking for surface action, Blue-Winged Olives (BWOs), Caddis, and small attractors are pulling in smaller trout that are starting to rise more regularly with longer daylight hours and warmer afternoons. Early morning and evening remain the best windows for dry fly activity, while midday fishing continues to produce below the surface.

Although the spring run of fresh fish has come and gone, anticipation is already building for the next seasonal movement. Traditionally, late April through May we can find large migratory holdovers, even in early summer, the Upper Owens holds a surprising number of quality fish for those willing to explore and fish methodically. The river’s combination of easy access, solitude, and the chance to hook a true Eastern Sierra trophy makes it a rewarding destination even outside of peak times. Be sure to tread lightly, handle fish with care, and enjoy the serenity this special stretch of water has to offer during the early summer season.

Lower Owens River Fly Fishing Report : Bishop, CA – 5.19.25

May 19, 2025
, , , , Fishing Reports

The Lower Owens River, just outside of Bishop, CA, continues to offer some of the best spring fly fishing in the Eastern Sierra. Recent snowmelt and runoff have pushed the river up to a healthy 280 cubic feet per second, creating vibrant flows that are still very fishable and are opening up fresh water and new holding areas for trout. The slightly stained water provides excellent cover, allowing anglers to get closer to fish without spooking them — a real advantage in this transitional season.

As the water rises, so does the bug activity. Caddisflies are now moving throughout the river, and the river is alive with insects in the evenings. Anglers are seeing explosive surface feeding right at dark. Dry fly action has been intense during this window, but does not last long. With trout aggressively keying in on caddis and mayfly patterns. A well-presented Elk Hair Caddis or CDC Caddis right at dusk can lead to some thrilling takes. Earlier in the day, nymphing remains productive, particularly in deeper runs and soft edges where trout are holding to conserve energy.

Despite the increase in flow, the river remains very accessible to both wading and floating anglers. These healthy conditions are breathing new life into the Lower Owens and spreading fish out across the system, offering a variety of productive water. With active wild brown trout with a few rainbows mixed in, strong insect activity, and dynamic evening dry fly fishing, it’s an exciting time to be on the river.

For those looking to experience the best of the Lower Owens this spring, now is the time. The combination of rising water, caddis hatches, and aggressive feeding behavior is setting up for one of the most memorable fishing windows of the year. We will monitor the flows closely from here on out to determine if and when they get out of control.
