2021 Season Trout Opener Fishing Report 4/26/21

Looking out to the horizon from a boat on a lake in the eastern sierra with snowy mountains in the distance.  

Opening day arrived with a late winter storm accompanying it. After a week of warmer weather, the general trout season opener was greeted with high winds which left boats stranded and created dangerous situations for many boaters. The further north you fished in Mono County, the windier it was for the weekend. Bridgeport Reservoir saw a lot of fish to the net that were willing to bite despite the inclement weather. Crowley Lake gave up a slower bite for fly fisherman opening day, but Sunday produced much better with various flies. The upcoming week will bring very warm temperatures by mid-week through Friday, and access is still limited to certain lakes due to leftover snowpack.

The East Walker is running at 45 cfs. These flows are still considered low for spring and once they increase, the fish will start to spread out and open up the river to more productive fishing areas. The deep pools are holding most of the fish for now, and drag free drifts with common mayfly and caddis nymphs are working. Smaller midges have also been productive along with egg patterns.

Hot Creek continues to fish well in both the canyon and Interpretive Site locations. SJ worms and Drifters’s Crawlers along with midges, pheasant tails and caddis larvae are working well. Dry fly hatches have been very fun with BWO’s being the main protein source and some caddis now showing up. Finding pockets of fish is the key to success.

The Upper Owens River has not shown any cutthroat moving in yet from the lake. Resident browns and rainbows are beginning to move around the river now as they transition to spring feeding patterns. Dry droppers and smaller nymphs have been working well in the riffles and deeper pools. Look for some exciting afternoon mayfly hatches that yield fun fishing with lighter weight rods.

Crowley Lake started off on the slower side for opening day for fly fishers. Sunday was a complete turn around as periods of high of pressure brought on some midge hatches and with it biting fish. Most of the fish coming to the net were rainbow and cutthroat trout in various sizes. Water is colder than usual for this time of year, so the fish are spread all over the lake at various depths. The coming warm weather this week should bring on some good hatches and we are finding fish as shallow as 10′. Hilton, Six Bays, and McGee have been producing during different times of the day. Best flies have been Dark Assassins #16-18, SD Chironomidges #16, Mud Candy #16, Copper Tiger #14 – 18, and Zebra Midges #16-18.
