Cache County Flood History

Flood — Mar 23, 2017

Heavy rain fell across Utah on March 23, leading to flooding in some locations across northern Utah.

Flood — Feb 7, 2017

Heavy rainfall and significant snowmelt through the month of February combined to produce flooding in multiple locations across far northern Utah.

Flood — Jun 2, 2017

Warm temperatures to begin the month of June led to rapid snowmelt near the Utah/Idaho border and flooding along the Logan River.

Flood — Jan 19, 2012

Deep Pacific moisture, combined with embedded weather disturbances moving through the region in the middle of January, resulted in heavy and wet snowfall in the mountains and mountain valleys of northern Utah. Occasional heavy rain was observed in the northern Utah valleys. This rain, when combined with frozen ground and snowmelt, produced flooding in portions of Cache Valley and Ogden Valley.

Flood — Jun 25, 2011

Unseasonably warm temperatures were observed again at the end of June, leading to even more river flooding across Utah. Waterways that flooded significantly during this time period included Little Cottonwood Creek, the Duchesne River, and Spring Creek in Providence, Utah.
