Kootenay Lake: the giant Gerrard rainbow trout, kokanee and bull trout in a long mountain lake, with a live level gauge.
Sources: Water Survey of Canada station 08NH064, Open-Meteo, solunar calculated for these coordinates.
Kootenay Lake rewards patience today, with cool water and short feeding windows. The gauge reads 531.33 m, holding steady. Today brings cloud cover, wind SSW around 3 km/h, rising pressure near 1002 hPa and a high of 16 °C. Water sits around 15 °C for the season (estimated). With the full moon, the solunar majors run 10:25 AM-12:25 PM and 10:25 PM-12:25 AM: the windows to build the day around.

Canada’s most stocked sport fish, in thousands of BC, Alberta and prairie lakes and in the famous rivers, the Bow first among them. Wild rainbows in the rivers; stocked fish in most small lakes. Fish shallower as the lake turns over; leeches and small lures along the shoals. Rivers fish best in the warmest hours.

Landlocked sockeye of the BC interior lakes: Okanagan, Kootenay, Shuswap and many smaller lakes. Schools in open water and feeds on plankton. Fish spawn in fall and leave the fishery.

The big char of cold, deep lakes: Lake Simcoe, the Kootenay and Shuswap systems, the northern lakes. A winter favourite through the ice, where the season allows. Fish come shallower after the lake turns over; cast or troll the shoals.

A native char of the cold mountain rivers of BC and Alberta, a predator of other fish. Protected in Alberta, where every bull trout must be released; limits vary by water in BC. Pre-spawn fish move upstream; large streamers in the pools.

Size and bag limits, closed seasons and protected areas are set by BC Freshwater Fishing and, in salt water and for salmon, by Fisheries and Oceans Canada, and change: confirm the current rules on the agency page linked from the British Columbia licence page before you keep anything.

Kootenay Lake is a lake in British Columbia, Canada, covered from the British Columbia reports and listed in all Canada waters.
Kootenay Lake is a long, deep lake in the Selkirk and Purcell mountains of southeastern British Columbia, more than a hundred kilometres from end to end, with the West Arm running to the city of Nelson. It is home to the Gerrard rainbow trout, a strain that grows to a remarkable size by feeding on the lake’s kokanee. The Water Survey of Canada gauge at Queens Bay, on the West Arm, supplies the lake level and the 30-day chart on this page.
Gerrard rainbows and bull trout are trolled for through much of the year, and kokanee are the lake’s food base and a fishery in their own right in summer. The lake has special rules, including a Kootenay Lake rainbow trout conservation surcharge, set out in the synopsis.
The main lake is trolled with plugs and bucktails for the big rainbows, often near the surface in the cooler months; the West Arm near Nelson and the north end near the Lardeau are well-known areas. The lake is big and exposed to wind.
Nelson, Kaslo and Balfour have marinas and launches, and a free ferry crosses the main lake between Balfour and Kootenay Bay. The lake is cold all year; dress for it. Kaslo, on the main lake, is a quiet base.
The lake level rises with the spring runoff and is regulated by dams downstream; fall, winter and spring are the prime trolling seasons for the big rainbows. Kokanee from the lake spawn in the Lardeau system in late summer, and the Meadow Creek spawning channel, near the north end, shows them in their red spawning colours.
The gauge shows the lake level; the chart shows the last 30 days. The water temperature estimate, labelled as one, helps place the fish in the water column. Pressure and sky build the score.
