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 Lac Des Roches: what the data says

4,520-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 155 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The rest of this page walks each species through its year, using the map's own scoring.

Lac Des Roches's chart carries 18 miles of bank, with a single island in the mix. A development index of 3.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 5% of the surface on the model — that's where the groceries are. End to end it runs roughly 5.3 mi, about 1.3 mi across. Cariboo Regional District claims this one. East Twin Lake sits 3 mi west — the closest neighbouring chart.

Burbot fishing at Lac Des Roches

Come spring, look for burbot tight to the bank in 25 to 70 ft. They move out to 50 to 120 ft in summer and finish the year down in 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 132 ft that scores prime in summer. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	25 to 70 ft	night & dusk	Deep basin (132 ft)	Glow jigging spoon + cut bait, Rattle bait (dark)
Summer	50 to 120 ft	night & midday	Deep basin (132 ft)	Heavy jig + cut bait
Fall	30 to 80 ft	night & dusk	Deep basin (132 ft)	Glow spoon + minnow head, Blade bait (slow)
Winter	15 to 60 ft	night & dusk	Deep basin (132 ft)	Glow tungsten + cut bait, Rattle spoon + minnow head

Kokanee fishing at Lac Des Roches

Spring kokanee on Lac Des Roches 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 Deep basin first on the milk run — a deep basin near 132 ft that grades good for spring. 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 (132 ft)	Small dodger + squid (pink), Wedding-ring spinner + corn
Summer	30 to 70 ft	dawn	Deep basin (132 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	Deep basin (132 ft)	Small glow jig + corn or maggot, Tiny spoon

Rainbow Trout fishing at Lac Des Roches

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, 39 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	Shallow bay flat (6 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	10 to 35 ft	dawn & dusk	Main-lake point (39 ft)	Casting spoon, Jerkbait over shoals
Winter	8 to 40 ft	dawn	open water	Jigging spoon, Tube jig (white)
