Hatch outlook

Callibaetis (Speckled Dun)Active window

Typical here: Aug 15 – Sep 15 · the smaller fall brood

nymphthe hours before the midday emergence — nymphs rise off the weed tops in a vertical zigzag that can take hours — sources split between slow 2–4 inch strips with long pauses and a quicker steady retrieve; carry both speeds
dunmidday, roughly 11am into early afternoon
spinnermid-to-late-morning falls

Trout browse the weed-bed edges knocking nymphs loose, then cruise the flats sipping duns at midday — the marquee western lake mayfly.

The midday emergence puts cruisers over weed flats in under 20 ft: a casting bubble with a #14 Callibaetis nymph retrieved dead-slow with pauses is the honest match. Between hatch hours, small spoons and #1 inline spinners along the weed edges and drop-offs pick off the same fish.

The event happens over weed flats and weed-bed edges in 20 ft of water or less

Chironomids (stillwater midges)Active window

Typical here: May 1 – Oct 31

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: Aug 25 – Oct 10 · peaks on crisp, bright fall days after the first cold snap

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

Grasshoppers (east-side summer)Active window

Typical here: Jun 15 – Sep 30

adultall day in high summer, best when afternoon wind knocks bugs onto the water

Pulls fish to the windward grassy banks and edges for months — fish the bank the wind blows ONTO.

The friendliest crossover of the summer: on lakes, drift the windward bank with a bubble-and-foam-hopper — the bubble's splash doesn't hurt a hopper presentation. On rivers, the same rig dead-drifted along the undercut grass banks, or small gold spinners under the banks between rises.

The event happens over grassy banks, undercut edges and windward shorelines

Fishing Conconully Reservoir: what the data says

374-acre reservoir near Okanogan County. The lake tops out around 50 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.

Brook Trout fishing at Conconully Reservoir

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. Summer brook trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 27 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 (1 ft)	Small inline spinner (gold), Tiny spoon
Summer	10 to 30 ft	dawn & dusk	Creek inflow (27 ft)	Small spoon fished deep, Trolled lake-clear wobbler + worm
Fall	2 to 15 ft	midday & dawn	Creek inflow (1 ft)	Small spoon (orange), Spinner
Winter	3 to 20 ft	dawn	Creek inflow (1 ft)	Small jigging spoon, Tungsten jig + plastic

Rainbow Trout fishing at Conconully Reservoir

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 27 ft, rated prime for summer 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	Break off the point (20 ft)	Inline spinner (silver), Small spoon
Summer	8 to 30 ft	dawn & dusk	Creek inflow (27 ft)	Dodger + spoon (deep troll), Flutter spoon

Winter	8 to 40 ft	dawn	Break off the point (20 ft)	Jigging spoon, Tube jig (white)

Kokanee fishing at Conconully Reservoir

Spring puts kokanee in skinny water — 10 to 30 ft is the zone. As the season builds they drop to 15 to 50 ft, wintering in 13 to 50 ft. Summer kokanee concentrate at Deep basin, a prime-rated deep basin around 50 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 (20 ft)	Small dodger + squid (pink), Wedding-ring spinner + corn
Summer	15 to 50 ft	dawn	Deep basin (50 ft)	Dodger + pink/orange squid on downrigger, Kokanee bug + corn

Winter	13 to 50 ft	dawn	Deep basin (50 ft)	Small glow jig + corn or maggot, Tiny spoon

Smallmouth Bass fishing at Conconully Reservoir

The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. The spot to know is Break off the point, a drop-off in about 20 ft of water that rates prime for smallmouth bass in winter. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	dawn & dusk	Main-lake point (1 ft)	Ned rig, Tube jig
Summer	10 to 30 ft	dawn & dusk	Break off the point (20 ft)	Drop shot (goby/minnow), Ned rig
Fall	8 to 25 ft	midday & dawn	Break off the point (20 ft)	Jerkbait, Blade bait
Winter	20 to 45 ft	midday	Break off the point (20 ft)	Blade bait, Hair jig

Largemouth Bass fishing at Conconully Reservoir

Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 20 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	dawn & dusk	Shallow bay flat (1 ft)	Spinnerbait, Chatterbait
