NRCan's Geographical Names database lists Cummings Creek as an official Kootenay Land District water (key JALPZ) at 49.762500, -114.875833. It drains into the
elk river on the same west-side branch as
telford creek,
ross creek,
rhodes creek,
will weaver creek and
whiting creek. Local fish-record extraction from the provincial beat model found 21 direct observations on Cummings itself: 7
westslope cutthroat trout, 5
brook trout, 4 bull trout, 3 Dolly Varden and 2 unidentified fish. Telford Creek carries the strongest child-creek signal, with 10 direct trout observations split between
rainbow and westslope cutthroat; Ross, Rhodes, Will Weaver and Whiting have named channels and contextual species lists but no direct observations on record, so they read as context-only water rather than confirmed fisheries.
