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 Stump Lake: what the data says

1,928-acre lake in Thompson-Nicola Regional District, British Columbia. The lake tops out around 70 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.

Drawn out, this is 1,875 acres of water rimmed by 13.1 miles of bank. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. About 11% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 5 mi, about 1.3 mi across. You'll find it in Thompson-Nicola Regional District. The nearest mapped water is Fraser Lake, 2 mi to the east.

Brook Trout fishing at Stump Lake

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 7 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 15 ft	dawn & dusk	Creek inflow (7 ft)	Small inline spinner (gold), Tiny spoon
Summer	10 to 30 ft	dawn & dusk	Creek inflow (7 ft)	Small spoon fished deep, Trolled lake-clear wobbler + worm
Fall	2 to 15 ft	midday & dawn	Creek inflow (7 ft)	Small spoon (orange), Spinner
Winter	3 to 20 ft	dawn	Creek inflow (7 ft)	Small jigging spoon, Tungsten jig + plastic

Cutthroat Trout fishing at Stump Lake

When the water first warms, cutthroat trout slide up into 3 to 15 ft. By summer they slide out to 10 to 35 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 7 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 15 ft	dawn & dusk	Creek inflow (7 ft)	Inline spinner (silver/gold), Small spoon
Summer	10 to 35 ft	dawn & dusk	Break off the point (32 ft)	Trolled spoon (small), Inline spinner
Fall	5 to 25 ft	dawn & dusk	Main-lake point (18 ft)	Casting spoon, Inline spinner
Winter	10 to 40 ft	dawn	Break off the point (32 ft)	Small jigging spoon, Marabou jig

Kokanee fishing at Stump Lake

Spring puts kokanee in skinny water — 10 to 30 ft is the zone. As the season builds they drop to 30 to 70 ft, wintering in 18 to 70 ft. Summer kokanee concentrate at Deep basin, a prime-rated deep basin around 60 ft. Warm-month bites cluster around early morning. A dodger + pink/orange squid on downrigger or a kokanee bug + corn covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 30 ft	dawn	Break off the point (32 ft)	Small dodger + squid (pink), Wedding-ring spinner + corn
Summer	30 to 70 ft	dawn	Deep basin (60 ft)	Dodger + pink/orange squid on downrigger, Kokanee bug + corn
Fall	5 to 40 ft	dawn	Creek inflow (7 ft)	Dodger + squid (deeper red/purple), Small spoon
Winter	18 to 70 ft	dawn	Deep basin (60 ft)	Small glow jig + corn or maggot, Tiny spoon

Rainbow Trout fishing at Stump Lake

In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. Creek inflow is the standout, an inflow / creek mouth at roughly 7 ft, rated prime for spring rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	5 to 20 ft	dawn & dusk	Creek inflow (7 ft)	Inline spinner (silver), Small spoon
Summer	8 to 30 ft	dawn & dusk	Creek inflow (7 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	10 to 35 ft	dawn & dusk	Main-lake point (18 ft)	Casting spoon, Jerkbait over shoals
Winter	8 to 40 ft	dawn	Break off the point (32 ft)	Jigging spoon, Tube jig (white)
