Teton County Flood History

Flood — Feb 24, 2023

During the late evening hours on February 24, a skier triggered avalanche occurred and deposited snow in Flat Creek.

Flood — Mar 23, 2018

A combination of rain and snow melt brought localized flooding to northern portions of the Jackson Valley. Several side roads were flooded and a home had basement flooding from the flood water.

Flash Flood — Aug 13, 2014

A slow-moving thunderstorm developed over the Teton Range and produced heavy rain along an axis parallel to and over Paintbrush Canyon. Rainfall amounts of one-half inch to one inch fell in 20 to 30 minutes in the steep-sided canyon. A large mudslide occurred as a result, washing out large sections of a popular trail.

Flood — Dec 11, 2011

An ice jam on Flat Creek in the southwest part of Jackson caused localized flooding of structures in two areas. The creek was flooded from the Snow King Avenue bridge to High School Road. Several homes had basement and garage flooding near Crabtree Lane and Shelby Lane. Also affected was an automotive repair shop on Berger Lane.

Flash Flood — Jul 26, 2007

Tropical moisture in association with the Southwest Monsoon streamed north into western Wyoming. Heavy rainfall in the foothills of the Teton Range west of Jackson triggered a debris flow.
