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 Green Lake: what the data says

6,820-acre lake in Thompson-Nicola Regional District, British Columbia. The lake tops out around 131 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. What follows comes from the same scoring engine that paints the spots above.

On the chart, Green Lake draws 7,030 acres inside 46.2 miles of shoreline — 14 islands included. With a shoreline index of 3.9, this water is all arms and coves — edge habitat well beyond its acreage. 30% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 11.2 mi with a 2.8-mi widest point. You'll find it in Thompson-Nicola Regional District. Closest neighbour on DepthScout: Tin Cup Lake, 3 mi south of here.

Brook Trout fishing at Green Lake

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Sharp break is the standout, a drop-off at roughly 16 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 15 ft	dawn & dusk	Shallow bay flat (6 ft)	Small inline spinner (gold), Tiny spoon
Summer	10 to 30 ft	dawn & dusk	Sharp break (16 ft)	Small spoon fished deep, Trolled lake-clear wobbler + worm
Fall	2 to 15 ft	midday & dawn	Rock reef (3 ft)	Small spoon (orange), Spinner
Winter	3 to 20 ft	dawn	Sharp break (16 ft)	Small jigging spoon, Tungsten jig + plastic

Kokanee fishing at Green Lake

In spring, kokanee run shallow here, mostly 10 to 30 ft. Summer pushes them deeper, 30 to 70 ft, and winter fish settle into 20 to 80 ft. Sharp break is the standout, a drop-off at roughly 16 ft, rated prime for spring kokanee. Time it for early morning. 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	Sharp break (16 ft)	Small dodger + squid (pink), Wedding-ring spinner + corn

Lake Trout fishing at Green Lake

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 111 ft, rated prime for summer lake trout. Plan around early morning in the warm months. 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	Main-lake point (33 ft)	Casting spoon over shoals, Jerkbait (shallow)
Summer	50 to 120 ft	dawn	Deep basin (111 ft)	White tube jig (deep), Magnum spoon on downrigger

Rainbow Trout fishing at Green Lake

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Winter rainbow trout concentrate at Sharp break, a prime-rated drop-off around 16 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
