Hatch outlook

Grasshoppers (east-side summer)Active window

Typical here: Jul 1 – Oct 15 · until the hard frosts of mid-October; on the Missouri, August hoppers fish mid-river, not the banks

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

Spruce MothActive window

Typical here: Jul 20 – Aug 31 · a conifer-forest event — it needs fir and lodgepole on the banks, so it's a Rock Creek / Blackfoot / upper Bitterroot specialty

adultmorning through midday — moths don't enter the water willingly — landings are sporadic and near the conifer banks; fish the imitation LOW in the film with minimal floatant, even fully drowned, with a little movement

When the moths show, just about every run produces — large trout key on them so hard that one pattern carries the whole box for two weeks.

Honest limit: a small drowned-surface moth has no lure analog. The workable rig is a casting bubble with a drowned moth pattern along the timbered banks in the morning; otherwise fish spinners early and late and leave the moth window to the film.

2–3 weeks at best, and day-to-day — fish key on the moths when they show and vanish with them

The event happens over banks under conifers — the moths rarely reach mid-river

Recommendations come from depth structure and seasonal species behavior. Treat them as a starting point, not a guarantee. Contours here are interpolated from real agency depth surveys (state DNR / USACE). Never use for navigation. Always check local regulations.

Fishing Dickey Lake (Flathead): what the data says

16-acre lake in Flathead County, Montana. The lake tops out around 16 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. The rest of this page walks each species through its year, using the map's own scoring.

Drawn out, this is 14 acres of water rimmed by 0.7 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. About 97% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. You'll find it in Flathead County. The nearest mapped water is Marion Lake, 2 mi to the southeast.

Largemouth Bass fishing at Dickey Lake (Flathead)

Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Top water on the chart: Main-lake point, a point in the 4 ft range, prime in fall. 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	Main-lake point (4 ft)	Spinnerbait, Chatterbait
Summer	5 to 16 ft	dawn & dusk	Break off the point (9 ft)	Texas-rigged 10" worm, Deep-diving crankbait
Fall	4 to 15 ft	midday & dawn	Main-lake point (4 ft)	Squarebill crankbait (shad), Spinnerbait
Winter	5 to 16 ft	midday	Break off the point (9 ft)	Blade bait, Jigging spoon

Cutthroat Trout fishing at Dickey Lake (Flathead)

When the water first warms, cutthroat trout slide up into 3 to 15 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 4 to 16 ft. If you only fish one area, make it Break off the point: a drop-off around 9 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 15 ft	dawn & dusk	Main-lake point (4 ft)	Inline spinner (silver/gold), Small spoon
Summer	5 to 16 ft	dawn & dusk	Break off the point (9 ft)	Trolled spoon (small), Inline spinner
Fall	3 to 16 ft	dawn & dusk	Main-lake point (4 ft)	Casting spoon, Inline spinner
