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 Susan Lake: what the data says

41-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 49 ft. The depth chart comes from British Columbia Fish and Wildlife Branch bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.

The outline encloses 41 acres, worked by 1.3 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 77% of this chart. End to end it runs roughly 0.5 mi, about 0.2 mi across. Cariboo Regional District claims this one. Judy Lake sits 1 mi southeast — the closest neighbouring chart.

Rainbow Trout fishing at Susan Lake

Spring rainbow trout on Susan Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. Put Break off the point first on the milk run — a drop-off near 30 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.

Season	Depth	Best window	Start at	Go-to baits
Spring	5 to 20 ft	dawn & dusk	Main-lake point (2 ft)	Inline spinner (silver), Small spoon
Summer	8 to 30 ft	dawn & dusk	Break off the point (30 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	10 to 35 ft	dawn & dusk	Break off the point (30 ft)	Casting spoon, Jerkbait over shoals
Winter	8 to 40 ft	dawn	Break off the point (30 ft)	Jigging spoon, Tube jig (white)

Bull Trout fishing at Susan Lake

Come spring, look for bull trout tight to the bank in 10 to 40 ft. They move out to 15 to 49 ft in summer and finish the year down in 14 to 49 ft. If you only fish one area, make it Deep basin: a deep basin around 40 ft that scores prime in summer. Best bite is early morning and the evening. A trolled plug on downrigger or a heavy jigging spoon is the honest summer answer here.

Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 40 ft	dawn & dusk	Break off the point (30 ft)	Large jointed plug, 6" swimbait (kokanee/trout pattern)
Summer	15 to 49 ft chart-limited; documented 30 to 90 ft	dawn & dusk	Deep basin (40 ft)	Trolled plug on downrigger, Heavy jigging spoon
Fall	5 to 35 ft	dawn & dusk	Break off the point (30 ft)	Large glide bait, Jointed plug
Winter	14 to 49 ft chart-limited; documented 20 to 70 ft	dawn	Break off the point (30 ft)	Heavy spoon (slow lift), Large soft swimbait
