Callibaetis (Speckled Dun) window is on — see the hatch outlook

Hatch outlook

Callibaetis (Speckled Dun)Active window

Typical here: May 1 – Oct 1 · multi-brood; a documented midsummer lull when surface temps push fish deep

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: Apr 25 – Oct 31 · end of April to the end of October at Crowley — the main food source for the entire season

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

Grasshoppers (east-side summer)Active window

Typical here: Jul 1 – Sep 30 · the East Walker and Upper Owens terrestrial program

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 Mamie Lake: what the data says

16-acre lake near Mono County. The lake tops out around 10 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.

The outline encloses 15 acres, worked by 0.9 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. Mono County claims this one. Mary Lake sits 1 mi southeast — the closest neighbouring chart.

Brook Trout fishing at Mamie Lake

Spring brook trout on Mamie Lake hold shallow, usually 1 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 2 to 10 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 9 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 10 ft	dawn & dusk	Shallow bay flat (3 ft)	Small inline spinner (gold), Tiny spoon
Summer	3 to 10 ft	dawn & dusk	Deep basin (9 ft)	Small spoon fished deep, Trolled lake-clear wobbler + worm
Fall	1 to 10 ft	midday & dawn	open water	Small spoon (orange), Spinner
Winter	2 to 10 ft	dawn	Deep basin (9 ft)	Small jigging spoon, Tungsten jig + plastic

Brown Trout fishing at Mamie Lake

Spring puts brown trout in skinny water — 1 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 1 to 10 ft. Summer brown trout concentrate at Shoreline break, a prime-rated drop-off around 5 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 10 ft	dawn & dusk	Shoreline break (5 ft)	Stickbait off planer boards (shallow), Small spoon along mud lines
Summer	3 to 10 ft	night & dawn	Shoreline break (5 ft)	Spoon at the thermocline, Deep stickbait (night)
Fall	2 to 10 ft	dusk & dawn	Shoreline break (5 ft)	Jerkbait over gravel, Casting spoon
Winter	1 to 10 ft	dawn	Shoreline break (5 ft)	Jigging spoon, Small stickbait (slow)

Rainbow Trout fishing at Mamie Lake

Early season rainbow trout use the shallows, holding in 3 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 2 to 10 ft. The chart's best answer is Shoreline break — drop-off, 5 ft, prime for winter. 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	3 to 10 ft	dawn & dusk	Shoreline break (5 ft)	Inline spinner (silver), Small spoon
Summer	3 to 10 ft	dawn & dusk	Shoreline break (5 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	3 to 10 ft	dawn & dusk	Shoreline break (5 ft)	Casting spoon, Jerkbait over shoals
Winter	2 to 10 ft	dawn	Shoreline break (5 ft)	Jigging spoon, Tube jig (white)
