Tendoy, the town this property stands in, in 1 storm report in 2026: 1 flood.
No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
The Lemhi River exceeded action stage on the 27th and reached minor flood stage on the 28th. This caused yard flooding south of Tendoy, between Mabee Lane and McDevitt Creek Road, though no homes were impacted. The river crested at 7.07 feet at 2:00 PM MST on the 29th at the Lemhi River near Lemhi gauge, then receded that evening as ice broke up.
