The water
Aosta Lower Lake is a small stillwater in the Elk River watershed, surveyed at 5.26 hectares by the province's fisheries inventory in August 1984, with no maximum depth on record. A short distance away in the same drainage sits its sibling, Aosta Upper Lake, a slightly smaller lake surveyed the same day. At this size the lake is close to all shoal: there is little dead water in the middle to skip past on the way to the good stuff.
The fishing
The stocking record here reads differently from a typical put-and-take lake. Most releases have been modest, around 1,000 fry a year, and the majority are logged as wild-origin fish rather than hatchery-reared: this looks like a low-density program built to hold up an existing population of westslope cutthroat rather than a heavy annual plant. The fish carry the CONNOR strain, the genetically pure westslope cutthroat broodstock line used widely across East Kootenay stillwaters.
Fished as a small stillwater, the pattern that works elsewhere on comparably sized East Kootenay lakes applies here: a chironomid pupa under an indicator worked slow over the shoal, or a leech pattern like a Woolly Bugger fished on a slow retrieve, covers the bulk of the productive water on a lake this small. Regional guidance for East Kootenay stillwaters also points to scuds and zooplankton as summer diet staples once the surface hatches taper off.
A conservation-style plant, not a put-and-take lake
Access and the rules
No public access details are confirmed for Aosta Lower Lake yet, so treat it as a regulation-and-access check before committing a day to it: confirm the road in, any walk-in distance, and parking locally before you go.

Stocking
For an angler judging whether the fishing is worth the drive, the stocking record is the closest thing to a fishing report this lake has. Aosta Lower has had 18 recorded releases since 1985, totalling roughly 35,100 westslope cutthroat fry, all CONNOR strain. The most recent plant was 1,000 fry on 2024-10-03. The chart below breaks the releases down by year.

Conditions
The lake sits at 5.26 hectares (about the size of seven Canadian football fields), small enough that wind and light can move the whole water column, not just a shoreline shoal. Depth was not recorded in the 1984 survey, so treat structure as unknown until confirmed on the water. No flow gauge or bathymetric chart is on file for this lake.
