Hatch outlook

Chironomids (stillwater midges)Active window

Typical here: Sep 1 – Oct 31 · the smaller fall second season — hatches continue on mild afternoons

nymphearly morning, start of the day — fish the bloodworm ON the bottom — 4–6 inches off the mud before the emergence starts
pupathe cool morning hours are prime — as the emergence builds, slide the pupa up to 12–15 inches off bottom under the indicator; a little wind chop does the jigging

Concentrates by DEPTH BAND and mud type, not a fixed spot: roughly 20–25 ft in spring, deeper midsummer, in against the feeder creeks in summer heat, 5–25 ft in fall. Match the band.

This one translates almost perfectly: a slip float with a 1/64–1/100 oz midge-pattern jig set 4–15 inches off bottom over a mud flat, dead-sticked with the chop doing the work. Depth control is everything — no moving lure imitates a hanging pupa; the float rig IS the technique.

The event happens over open mud flats alongside weedlines, channels and basin edges; feeder-creek mouths in summer heat

Water boatman fall flightsActive window

Typical here: Sep 1 – Oct 31 · fall mating flights on calm sunny days — 'raindrops hitting the water'; a smaller spring flight is documented right after ice-off

adultmiddday-ish on calm, sunny fall days — the fishable moment is the splashdown: boatmen dive in headfirst trailing an air bubble and make repeated trips back to the surface — a fly or lure that dives nose-first on the drop imitates exactly this

Takes are seldom subtle — trout ravage boatmen as they hit the water and during their subsurface runs.

Tailor-made for hardware: a small 1/16 oz silver-bellied spoon or jig cast AT the rings of a splashdown sinks headfirst exactly like the natural — twitch-pause it back through the top few feet. On flight days fan-cast the shallow weed margins.

The event happens over near-shore shallows, weed beds and shoal margins on calm sunny fall afternoons

Scuds (Gammarus shrimp)Active window

Typical here: Jan 1 – Dec 31 · year-round — the biomass behind the Kamloops fishery's growth rates; most important early spring and again in fall as dying weed cover exposes them

adultall day, year-round — best when weed cover is thin (early spring, late fall) — quick 1-inch 'shrimpy' strips along the weed beds and marl; in fall a subtle slow retrieve just off the bottom

Not an event — the pantry. Scud water is why these lakes grow big rainbows; fish them when nothing is hatching.

No hardware imitates a half-inch freshwater shrimp well — this is a jig game: a small olive/tan micro-jig under a slip float worked along the weed edges, or fished just off bottom in fall. Otherwise treat scud water as the signal that the lake grows big fish.

The event happens over weed beds, chara and marl flats and shoal-zone debris in calcium-rich lakes

Leeches (stillwater staple)Active window

Typical here: Jan 1 – Dec 31 · year-round — the go-to at ice-off before the chironomids start, and again through fall

adultany hour; low light and the cool ends of the season fish best — slow steady hand-twist or 2–3 inch pulls — in fall a slow steady pull outfishes a fast strip — or hang a balanced leech under an indicator

Baseline food, not an event — the honest 'nothing is hatching' answer on every interior lake, bracketing the season at ice-off and late fall.

The most spin-friendly item on the menu, with agency-documented tactics: slow-troll a Worden's Triple Teazer or Panther Martin along the drop-offs (the BC agency's own recommendation), or fish a black or olive marabou jig under a slip float over the shoal edge.

The event happens over shoal-zone vegetation, woody debris and rock, sliding to the drop-offs by day

Fishing Alouette Lake: what the data says

3,914-acre lake in Fraser Valley Regional District, British Columbia. The lake tops out around 522 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.

Drawn out, this is 3,914 acres of water rimmed by 24.2 miles of bank. A development index of 2.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 0% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 10.5 mi, about 1.4 mi across. The water lies in Fraser Valley Regional District. Closest neighbour on DepthScout: Morgan Lake, 3 mi east of here.

Cutthroat Trout fishing at Alouette Lake

Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. They move out to 10 to 35 ft in summer and finish the year down in 10 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 235 ft that scores good in summer. Best bite is early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 15 ft	dawn & dusk	open water	Inline spinner (silver/gold), Small spoon
Summer	10 to 35 ft	dawn & dusk	Break off the point (235 ft)	Trolled spoon (small), Inline spinner
Fall	5 to 25 ft	dawn & dusk	Main-lake point (131 ft)	Casting spoon, Inline spinner
Winter	10 to 40 ft	dawn	Break off the point (235 ft)	Small jigging spoon, Marabou jig

Kokanee fishing at Alouette Lake

In spring, kokanee run shallow here, mostly 10 to 30 ft. Midsummer fish sit out in 30 to 70 ft before dropping to 20 to 80 ft for winter. Summer kokanee concentrate at Offshore hump, a prime-rated offshore hump around 56 ft. Fish it in early morning and you'll meet the bite. You won't need more than a dodger + pink/orange squid on downrigger or a kokanee bug + corn most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 30 ft	dawn	Deep basin (444 ft)	Small dodger + squid (pink), Wedding-ring spinner + corn
Summer	30 to 70 ft	dawn	Offshore hump (56 ft)	Dodger + pink/orange squid on downrigger, Kokanee bug + corn
Fall	5 to 40 ft	dawn	open water	Dodger + squid (deeper red/purple), Small spoon
Winter	20 to 80 ft	dawn	Offshore hump (78 ft)	Small glow jig + corn or maggot, Tiny spoon

Lake Trout fishing at Alouette Lake

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 50 to 120 ft, wintering in 20 to 80 ft. Summer lake trout concentrate at Offshore hump, a prime-rated offshore hump around 78 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 40 ft	dawn & dusk	Offshore hump (49 ft)	Casting spoon over shoals, Jerkbait (shallow)
Summer	50 to 120 ft	dawn	Offshore hump (78 ft)	White tube jig (deep), Magnum spoon on downrigger
Fall	10 to 50 ft	dusk & dawn	Offshore hump (49 ft)	Heavy casting spoon, Jigging rap over reefs
Winter	20 to 80 ft	dawn	Offshore hump (78 ft)	White tube jig, Airplane jig

Rainbow Trout fishing at Alouette Lake

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Shallow bay flat is the standout, a feeding flat at roughly 6 ft, rated good for spring rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	5 to 20 ft	dawn & dusk	Shallow bay flat (6 ft)	Inline spinner (silver), Small spoon
Summer	8 to 30 ft	dawn & dusk	Shallow bay flat (6 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	10 to 35 ft	dawn & dusk	open water	Casting spoon, Jerkbait over shoals
Winter	8 to 40 ft	dawn	Break off the point (235 ft)	Jigging spoon, Tube jig (white)
