Upper Owens River Fly Fishing Report : Mammoth Lakes, CA – 9.15.21

The Upper Owens River continues running at a low flow of around 58cfs. Nothing super excitingly new to report here except the fact that the nights are much cooler and soon we will be able to cast our hand tied flies into a hole with the possibility of hooking into a trout that will completely test every fly fishing skill you have. These trout could also possibly be the largest freshwater fish you will hook in your life! For the last few years we have experienced the presence of some very large Crowley trout; Rainbows, Browns, and Lahonton Cutthroat trout will all be making their way up the river to spend the winter season in the amazing and scenic waters of the Upper Owens making nothing short of a fly fishing paradise for us fly anglers. For now, the river is still worth fishing as we get reports from personal experience, and through the shop of random large fish who have decided to take up residence in the Upper O all year long!

Upper Owens River Fly Fishing Report : Mammoth Lakes, CA – 4.7.2021

Flowing just outside of Mammoth Lakes, CA, The Upper Owens river remains one of the most beautiful fly fishing destinations in the country. Water is low and a bit more clear above the Hot Creek confluence, with the water having a small off colour haze below the creeks main entry point. Temperatures in the valley have ramped up here this last week, which leads us to think of the soon to come runoff which will bring the river up to a faster flowing status. This can be good or bad for the fishing. Yet, always good for the fish. Right now the large fish are still throughout the entire system and have now had some time in these deeper holes, runs, and riffles. These large and wise Crowley Trout have now seen relentless flies passed in front of them. Now, you need not only to find and fool the trout, you must do it better than all fisherman before you that tried their skills on these legendary fish. Attractor nymphs, Jig-Nymphs, Non- traditional SJ worms, and small midges and mayflies will give you a good shot at these fish. Some random bug attacks on the surface do take place. But do not get to excited about it! There is no rhyme or reason to why or when they decide to come up, but it sure is exciting! A well versed streamer fisherman can also have a great day on this water. A long leader with a heavy fly or a sink tip will fish best in this smaller river. We look for a different run of fish to enter this spring as some leave back to Crowley Lake.

Upper Owens River Fly Fishing Report : Mammoth Lakes, CA – 11.24.20

The Trophy trout season on the Upper Owens right below Mammoth Lakes is showing us some absolute stunning large Trout. From the bridge up the big fish are spread out throughout the system. Some days we fish a long time without a fish, but, then it happens. These fish are large and bright. The fight is a tug of war that one must be prepared for. Giving and taking line when they let you is what you must do to bring these behemoths to the net. Many sorts of semi- steelhead and trout type patterns will trick these fish to get them to eat and run. Streamers work, but must be constantly tended to and fished appropriately without spooking the fish. This is one of our favorite times of the year as we do not need to travel to hook up with a Trophy Trout!

The Upper Owens just below Mammoth Lakes California has the Meat! Flows are low and clear as usual for this time of year making for some spooky quarry. Cold weather hit hard this last week pushing some more fish towards the north and upstream. Days are clear and the smoke is completely gone while Mammoth Mountain can be seen in the distance covered in snow. Fish the deepest and darkest areas of the Upper Owens. Time appropriation is crucial as these fish are more characteristic of Steelhead than Rainbow Trout. A few Brown Trout are also coming up with the mix of Rainbows and are a pleasure to catch. Stay tuned for many more updates on this amazing fishery throughout the winter.

Upper Owens River Fly Fishing Report : Mammoth Lakes, CA – 9.12.20

The Upper Owens River Fly Fishing near Mammoth Lakes, CA has changed a bit since the Canadian cold sweep earlier this week. The river still flows at a late summer subtle level. Water clarity is as usual always fishable, and water temps remain within healthy levels. The Hoppers are still there but they struggle to get moving until the sun warms them at a later time depending on the day. Before that anxiously awaited moment we end up going down under the water with all sorts of attractor nymphs and streamers. The entire river holds fish, read the water to appropriate your time wisely and spend it in the fishiest looking holding water. As we feel the cooler mornings rolling in we look forward to the fish of the Fall that come up river.

Upper Owens River Fly Fishing Report : Mammoth Lakes, CA – 10.7.19

The Upper Owens has undergone a few changes since my last report. Weather has changed in the direction of winter, dropping the temperatures around the Mammoth Lakes area extending down to the grassy plains of the Upper Owens River. Hoppers can still be seen, but numbers are diminishing during the coldness of the nights. However, after eating the leggy creatures for a solid few months it seems that they still hold some residual memory of the big insects. The Upper Owens trout will still come up and eat a hopper for the time being, during the warmer parts of the day. Some of the anticipated big boys coming out of the lake have been spotted in the deeper holes of the river. We will have to see what this year holds as these this spectacular run of fish swims up the Upper Owens from Crowley Lake from now and forward. Stay tuned!

Upper Owens River Fly Fishing Report : Mammoth Lakes CA – 4.17.19

The Upper Owens River seasonal large Trout continue to haunt its darkest areas is full post spawn mode. Making them back in to aquatic bug eaters! The river remains in about the same condition as my last report although, either good or bad, we have seen clearer water conditions due to the lack of precipitation these last couple of weeks. Fish continue to haunt the deepest and darkest portions of the Upper. Cast out similar patterns as mentioned in my previous few reports. With Mammoth in the distance and the snow almost gone on Long Valley Floor, you could say the Upper Owens is pretty close to paradise for most of us. It will be interesting to see what is going to occur in the next few weeks as it warms up and cool water flows heavier from up high…..
