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 Allison Lake: what the data says

152-acre lake in Okanagan-Similkameen Regional District, British Columbia. The lake tops out around 128 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:

Allison Lake maps at 152 acres behind 3.4 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. 17% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1.4 mi, about 0.3 mi across. Okanagan-Similkameen Regional District claims this one. Its nearest charted neighbour, Round Lake, is 2 mi to the south.

Kokanee fishing at Allison Lake

Spring kokanee on Allison Lake hold shallow, usually 10 to 30 ft. They move out to 30 to 70 ft in summer and finish the year down in 20 to 80 ft. Put Break off the point first on the milk run — a drop-off near 58 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a dodger + pink/orange squid on downrigger or a kokanee bug + corn.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 30 ft	dawn	Deep basin (109 ft)	Small dodger + squid (pink), Wedding-ring spinner + corn
Summer	30 to 70 ft	dawn	Break off the point (58 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	Break off the point (58 ft)	Small glow jig + corn or maggot, Tiny spoon

Lake Trout fishing at Allison Lake

Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 109 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 40 ft	dawn & dusk	Main-lake point (32 ft)	Casting spoon over shoals, Jerkbait (shallow)
Summer	50 to 120 ft	dawn	Deep basin (109 ft)	White tube jig (deep), Magnum spoon on downrigger
Fall	10 to 50 ft	dusk & dawn	Main-lake point (32 ft)	Heavy casting spoon, Jigging rap over reefs
Winter	20 to 80 ft	dawn	Break off the point (58 ft)	White tube jig, Airplane jig

Rainbow Trout fishing at Allison Lake

Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Main-lake point — point, 32 ft, prime for fall. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

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	Main-lake point (32 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	10 to 35 ft	dawn & dusk	Main-lake point (32 ft)	Casting spoon, Jerkbait over shoals
Winter	8 to 40 ft	dawn	Break off the point (58 ft)	Jigging spoon, Tube jig (white)

Lake Whitefish fishing at Allison Lake

The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. The spot to know is Break off the point, a drop-off in about 58 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

Season	Depth	Best window	Start at	Go-to baits
Spring	15 to 45 ft	midday & dawn	Shallow bay flat (6 ft)	Small jig + waxworm, Blade bait (small)
Summer	40 to 90 ft	dawn	Break off the point (58 ft)	Blade bait vertical, Small jigging spoon
Fall	8 to 30 ft	dusk	Main-lake point (32 ft)	Small spoon (gold), Jig + plastic larva
Winter	25 to 70 ft	midday & dawn	Break off the point (58 ft)	Jigging spoon + bead chain, Tungsten jig + waxie
