Phillips 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 Phillips Lake: what the data says

151-acre lake near Mason County. The lake tops out around 25 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. Every species below gets its seasonal read from the same numbers driving the chart.

The drawn water covers 151 acres wrapped in 2 miles of bank. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 61% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.8 mi end to end and 0.5 mi across at its widest. It sits in Mason County. Its nearest charted neighbour, Spencer Lake, is 1 mi to the north.

Brook Trout fishing at Phillips Lake

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 3 to 20 ft. Put Creek inflow first on the milk run — an inflow / creek mouth near 25 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 15 ft	dawn & dusk	Main-lake point (1 ft)	Small inline spinner (gold), Tiny spoon
Summer	8 to 25 ft	dawn & dusk	Creek inflow (25 ft)	Small spoon fished deep, Trolled lake-clear wobbler + worm
Fall	2 to 15 ft	midday & dawn	Main-lake point (1 ft)	Small spoon (orange), Spinner
Winter	3 to 20 ft	dawn	Break off the point (9 ft)	Small jigging spoon, Tungsten jig + plastic

Rainbow Trout fishing at Phillips Lake

Spring rainbow trout on Phillips Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 7 to 25 ft, and by winter most fish are in 5 to 25 ft. The chart's best answer is Creek inflow — inflow / creek mouth, 25 ft, prime for summer. Prime time lands in 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	Break off the point (9 ft)	Inline spinner (silver), Small spoon
Summer	7 to 25 ft	dawn & dusk	Creek inflow (25 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	7 to 25 ft	dawn & dusk	Old creek channel (25 ft)	Casting spoon, Jerkbait over shoals
Winter	5 to 25 ft	dawn	Break off the point (9 ft)	Jigging spoon, Tube jig (white)
