NRCan's Geographical Names database lists Telford Creek as an official Kootenay Land District water (key JBHAY) at 49.786389, -114.974167. It drains into
cummings creek, which in turn joins the
elk river on the west side of the valley. Local fish-record extraction found 10 direct observations on Telford itself: 5
rainbow trout and 5
westslope cutthroat trout, the strongest child-creek signal in the Cummings cluster, where Ross, Rhodes, Will Weaver and Whiting creeks carry named channels but no direct observations on record. The 2018 Elk Valley aquatic cumulative-effects report treats Telford Creek as its own assessment watershed, flagging stream crossings, road density, riparian disturbance and temperature as the key aquatic-risk indicators in this part of the valley.
