Pass Lake Depth Map & Fishing Spots (WA)

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 Pass Lake: what the data says

105-acre lake near Skagit County. The lake tops out around 20 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.

The outline encloses 105 acres, worked by 1.7 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. About 68% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.7 mi long by 0.3 mi wide at the broadest reach. Skagit County claims this one. Its nearest charted neighbour, Lake Campbell, is 2 mi to the northeast.

Brown Trout fishing at Pass Lake

Start shallow in spring: brown trout sit in 2 to 20 ft that time of year. They don't go far with the seasons — 6 to 20 ft covers summer, 3 to 20 ft covers winter. The spot to know is Break off the point, a drop-off in about 14 ft of water that rates prime for brown trout in summer. Warm-month bites cluster around after dark and early morning. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 20 ft	dawn & dusk	Main-lake point (1 ft)	Stickbait off planer boards (shallow), Small spoon along mud lines
Summer	6 to 20 ft	night & dawn	Break off the point (14 ft)	Spoon at the thermocline, Deep stickbait (night)
Fall	3 to 20 ft	dusk & dawn	Main-lake point (1 ft)	Jerkbait over gravel, Casting spoon
Winter	3 to 20 ft	dawn	Break off the point (14 ft)	Jigging spoon, Small stickbait (slow)

Rainbow Trout fishing at Pass Lake

Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Through summer count on 5 to 20 ft; the winter hold is 4 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	5 to 20 ft	dawn & dusk	Break off the point (14 ft)	Inline spinner (silver), Small spoon
Summer	5 to 20 ft	dawn & dusk	Break off the point (14 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	6 to 20 ft	dawn & dusk	Break off the point (14 ft)	Casting spoon, Jerkbait over shoals
Winter	4 to 20 ft	dawn	Break off the point (14 ft)	Jigging spoon, Tube jig (white)
