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 Martin Lake (Lincoln): what the data says

18-acre lake in Lincoln County, Montana. The lake tops out around 10 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 season-by-season read for each species follows, from the map's own numbers.

Shoreline on the chart totals 1.2 miles. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Figure 0.5 mi of water from one end to the other. You'll find it in Lincoln County. The nearest mapped water is Murphy Lake, 1 mi to the southwest.

Brook Trout fishing at Martin Lake (Lincoln)

Start shallow in spring: brook trout sit in 1 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 2 to 10 ft covers winter. The spot to know is Deep basin, a deep basin in about 10 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.

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

Northern Pike fishing at Martin Lake (Lincoln)

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 10 ft; cold water stacks them in 3 to 10 ft. Break off the point is the standout, a drop-off at roughly 5 ft, rated prime for fall northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
