Leavitt Meadows and Pickel Meadow (California)
The West Walker starts at Tower Lake in the Hoover Wilderness and collects in Leavitt Meadows on Highway 108 west of Sonora Junction, a two-mile meadow with something like four miles of meandering channel, pools and connecting riffles. It holds brook trout and stocked rainbows, and the fish run small. Below the meadow the river drops through a canyon to Pickel Meadow, home of the Marine Corps Mountain Warfare Training Center, then falls again to meet the Little Walker River near the junction of Highways 108 and 395. Sonora Pass closes for the winter, so this upper water is a summer and early fall proposition.
Walker Canyon: Sonora Bridge to Walker (California)
From Sonora Junction the river turns north beside US 395 and drops through roughly six miles of canyon pocket water before emerging into Antelope Valley at the town of Walker. Chris Flat and Bootleg campgrounds and a string of highway pullouts give easy access; the water right at the road is stocked and heavily fished, and the fishing improves where the river pulls away from the pavement.
This is the reach the January 1997 flood rebuilt. A warm subtropical storm from December 30, 1996 through January 3, 1997 dropped over 11 inches of rain at Sonora Pass on a deep snowpack, and USGS estimated the peak at the Coleville gauge at about 12,500 cfs, well above the 100-year flood. Roughly 10 miles of US 395 in Walker Canyon were torn apart. Caltrans let two emergency contracts the next month, one for the highway and one for river habitat, and the road reopened in June 1997. The river channel through the canyon and the town of Walker was rebuilt in that work, and Mono County says the fishery has improved steadily since.
Antelope Valley, Topaz and the Nevada canyons
Below Walker the river crosses rangeland past Coleville to Topaz Lake, where the Walker River Irrigation District diverts water into the offstream reservoir. This valley water holds some larger fish but is mostly private and hard to reach. The Coleville gauge this page follows sits at the head of the valley, upstream of the diversions.
In Nevada the West Walker runs through Smith Valley to Wellington, where NDOW lists two main public reaches: about a mile of Hoye Canyon upstream from Wellington, and the BLM Wilson Canyon recreation area on Highway 208, which allows primitive camping. Both are stocked with rainbows and browns, and Hoye Canyon can also produce largemouth and smallmouth bass. Much of Smith and Mason valleys is private, and the river is non-navigable in Nevada, so the bed inside private ranches is private too. NDOW rates it a put-and-take fishery with no minimum flow requirement, wadeable from November into early April and high with runoff and irrigation demand through spring and summer.
The main-stem Walker River to Walker Lake
The West Walker joins the East Walker in Mason Valley south of Yerington and the main-stem Walker River continues northeast, then bends south through the Walker River Paiute Reservation at Schurz and Weber Reservoir to end in Walker Lake near Hawthorne. Confirm access and tribal permit rules before fishing the reservation reach. The lake is a terminal basin whose dissolved solids now exceed 21,000 mg/L; NDOW says Lahontan cutthroat no longer occur there and none have been reported by anglers or surveys since the winter of 2010, so there is no lake fishery to plan a trip around.
Rainbows, browns, brookies and whitefish
CDFW plants rainbows in the West Walker's roadside sections through the summer, and Mono County adds fish paid for by its fishing derbies, so most of what you catch along US 395 is hatchery rainbow with a share of browns. Wild browns hold in the deeper canyon runs and undercut banks between Walker and Coleville, brook trout live in the headwater meadows, and mountain whitefish turn up in the lower river. Lahontan cutthroat and whitefish were the native fish, and a stray cutthroat is possible but rare. In Nevada, NDOW planned 10,000 rainbows and 2,000 browns for the West Fork in 2026, stocking from March until water warms in late June and again in fall.
Runoff usually peaks in May and June and the river is often unfishable then. Once flows drop, the canyon and valley water fish well on caddis, golden stones and attractor dries in summer, hoppers along the meadows, and Blue-Winged Olives in spring and fall. Streamers and weighted nymphs are the answer in higher water.
Season and regulations
California Fly Fisher says the West Walker becomes productive once runoff passes and flows drop to 150 cfs or less, and Mono County's fishing page calls anything under 200 cfs good wet-wading water. By late summer the river settles to base flows of a few dozen cfs and fishing tails off as it dwindles and warms. This page compares the USGS gauge near Coleville (10296500), at the mouth of Walker Canyon, to 40 to 150 cfs; the Nevada reaches are read at the Hoye Bridge gauge and run higher in irrigation season.
In California the main stem carries no special regulation, so the statewide stream rules apply: the last Saturday in April through November 15, five trout, no gear restriction; November 16 through the Friday before the last Saturday in April is zero trout with artificial lures and barbless hooks only. Some tributaries differ: Mill Creek above Lost Cannon Creek and Wolf Creek are flies only with barbless hooks and zero trout, and Silver Creek is closed all year. In Nevada the West Walker is open all year under general regulations, five trout, 10 mountain whitefish and 15 warmwater fish. Each state requires its own license. Check the current CDFW and NDOW regulations before you go.
