Jette Lake Depth Map & Fishing Spots (MT)

Target species

Species estimated from nearby surveyed lakes. No fish-species survey is on record for this water, so these species aren't a confirmed catch list. They're an informed estimate: the species listed for the nearest surveyed lakes in the same region, kept only where they fit this lake's depth and habitat. Treat them as what's likely present. (The depth chart itself is real surveyed bathymetry.) How we estimate species →

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 Jette Lake: what the data says

29-acre lake in Lake County, Montana. The lake tops out around 31 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. Below is the species-by-species picture, pulled from the same data the map uses.

The outline encloses 28 acres, worked by 1 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 41% of the surface — that's where the groceries are. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. It sits in Lake County. Flathead Lake sits 9 mi north — the closest neighbouring chart.

Rainbow Trout fishing at Jette Lake

When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 6 to 31 ft. If you only fish one area, make it Break off the point: a drop-off around 25 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.

Season	Depth	Best window	Start at	Go-to baits
Spring	5 to 20 ft	dawn & dusk	Main-lake point (5 ft)	Inline spinner (silver), Small spoon
Summer	8 to 30 ft	dawn & dusk	Break off the point (25 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	9 to 31 ft	dawn & dusk	Break off the point (25 ft)	Casting spoon, Jerkbait over shoals
Winter	6 to 31 ft	dawn	Break off the point (25 ft)	Jigging spoon, Tube jig (white)

Cutthroat Trout fishing at Jette Lake

The spring pattern is a shallow one: cutthroat trout in 3 to 15 ft. Midsummer fish sit out in 9 to 31 ft before dropping to 8 to 31 ft for winter. The spot to know is Break off the point, a drop-off in about 25 ft of water that rates prime for cutthroat trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a trolled spoon (small) or an inline spinner gets it done.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 15 ft	dawn & dusk	Main-lake point (5 ft)	Inline spinner (silver/gold), Small spoon
Summer	9 to 31 ft	dawn & dusk	Break off the point (25 ft)	Trolled spoon (small), Inline spinner
Fall	5 to 25 ft	dawn & dusk	Main-lake point (5 ft)	Casting spoon, Inline spinner
Winter	8 to 31 ft	dawn	Break off the point (25 ft)	Small jigging spoon, Marabou jig

Yellow Perch fishing at Jette Lake

In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 31 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 11 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	Shallow bay flat (11 ft)	Small jig + curly tail, Perch-pattern micro crank

The chart's best answer is Shallow bay flat — weed flat, 11 ft, prime for winter. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
