About Slocan River

The Slocan is a wild rainbow trout river with a comeback story. It drains the south end of Slocan Lake at Slocan City and runs about 57 km south past Winlaw and Passmore to the Kootenay at Shoreacres, between Nelson and Castlegar. The rainbows crashed in the 1980s and the province closed the river in 1993. It reopened in the mid-1990s as catch and release only, and it still is: every trout and char goes back. Mountain whitefish and bull trout live here too. Do not plan on cutthroat: the provincial records hold a single one, from 1986.

The upper river below Slocan City is broad, flat water that bends slowly through farmland. Below Winlaw it speeds up, with rapids under the Winlaw bridge and swift, rocky water from Passmore to Crescent Valley. Region 4 streams are closed April 1 to June 14, so the season opens on the snowmelt, which peaks in June and drops through July. Read the Crescent Valley gauge for the trend. Summer is the hard part: the river is warmest from late July to mid-August, and in hot years the local Streamkeepers' loggers read over 20 °C on many days. The river is closed from noon to midnight from July 15 to August 31, so fish the mornings. Local accounts describe chironomids, mayflies, stoneflies, salmonflies and caddis, but no one has published a dated hatch calendar for this river.

On a hot afternoon the Slocan is a float river for tubers and paddleboarders, and the Slocan Valley Rail Trail runs 52 km beside it from South Slocan to Slocan, with road bridges across the river at Crescent Valley, Slocan Park, Passmore, Winlaw, Perry's Siding and Slocan. Farms and homes line much of the floodplain, so use the bridges and the rail trail to reach the water. Lemon Creek, which held more trout than any other index site in the 2005 counts, is closed to fishing. Nelson and Castlegar are each about 45 minutes from Winlaw, and the nearest fly shop is in Castlegar.

Sections

3 reaches

Slocan City to Winlaw

Wade & FloatRainbow Trout

The river leaves Slocan Lake at Slocan City as broad, slow water and bends through farmland past the Gravel Pit Road bridge, the Lemon Creek confluence and Perry's Siding to Winlaw. Easy wading at summer flows. Lemon Creek itself is closed to all fishing.

Best for: Wild rainbow trout on dry flies and nymphs in the slow runs, catch and release, best in the mornings in summer.

Winlaw to Passmore

Wade & FloatRainbow Trout · Whitefish

Faster water. Rapids start below the Winlaw bridge, where habitat structures were placed in the river, and the Little Slocan joins just above the Passmore bridge. The rail trail follows the east bank.

Best for: Rainbow trout in the pocket water and riffles, and mountain whitefish, catch and release.

Passmore to the Kootenay

Wade & FloatBull Trout · Rainbow Trout · Whitefish

Swift water in a narrow, winding valley with rocky banks, past Slocan Park, Crescent Valley and the gauge to the Kootenay at Shoreacres. Bridges at Slocan Park, Crescent Valley and Highway 3A give access.

Best for: Rainbow trout and bull trout in the deeper runs, mountain whitefish, catch and release.

Best seasons

The season opens June 15 on falling snowmelt, often still near 300 m³/s at Crescent Valley, and the river wades best from late July, when it drops under about 70 m³/s. Mornings are the rule in late July and August, when the afternoon closure applies and the water passes 19 to 20 °C. September and October bring cooler water and lower flows, near 35 m³/s. About 15 °C is best for the rainbows, and over 20 °C stresses them.
