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 Seeley Lake: what the data says

1,025-acre lake near Seeley Lake. The lake tops out around 120 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. What the data behind the map says about each species, season by season:

Drawn out, this is 1,036 acres of water rimmed by 8.3 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 9% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 3.5 mi of water from one end to the other, 0.8 mi at the beam. You'll find it in Missoula County. Closest neighbour on DepthScout: Tuppers Lake, 3 mi south of here.

Kokanee fishing at Seeley Lake

The spring pattern is a shallow one: kokanee in 10 to 30 ft. As the season builds they drop to 30 to 70 ft, wintering in 20 to 80 ft. Top water on the chart: Break off the point, a drop-off in the 26 ft range, prime in spring. Time it for early morning. Summer baits: a dodger + pink/orange squid on downrigger or a kokanee bug + corn gets it done.

Season	Depth	Best window	Start at	Go-to baits
Spring	10 to 30 ft	dawn	Break off the point (26 ft)	Small dodger + squid (pink), Wedding-ring spinner + corn
Summer	30 to 70 ft	dawn	Break off the point (26 ft)	Dodger + pink/orange squid on downrigger, Kokanee bug + corn
Fall	5 to 40 ft	dawn	Break off the point (26 ft)	Dodger + squid (deeper red/purple), Small spoon
Winter	20 to 80 ft	dawn	Break off the point (26 ft)	Small glow jig + corn or maggot, Tiny spoon

Lake Whitefish fishing at Seeley Lake

Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. They move out to 40 to 90 ft in summer and finish the year down in 25 to 70 ft.

A blade bait vertical or a small jigging spoon is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	15 to 45 ft	midday & dawn	Break off the point (26 ft)	Small jig + waxworm, Blade bait (small)
Summer	40 to 90 ft	dawn	Break off the point (26 ft)	Blade bait vertical, Small jigging spoon

You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

Main-lake point is the standout, a point at roughly 11 ft, rated prime for fall largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
