Park County Flood History

Flood — Mar 25, 2019

Flooding occurred across many areas of south central and southeast Montana during the latter portions of the month. A considerable snow cover existed through the month. Surface and sub-surface ground temperatures remained frozen through the last week of March. Warming temperatures resulted in this snow to quickly melt. Widespread flooding occurred due to the snow melt not being able to soak in...

Flood — May 27, 2014

The snowpack during most of the month of May was around 150% of average. There was significant melting of the snowpack below 8000 feet during the month. The melting snowpack resulted in rising river levels and river flooding. The main impacts of the high river flows were fast flows, low-land flooding and bank erosion.

This warm-up resulted in snowmelt and ice-jam flooding over area rivers, creeks and streams that continued into the middle of the month. While many areas experienced flooding, the locations that were most impacted by flooding included Park County, a...

Another system passed to the south on the 23rd and 24th, continuing the precipitation across the area. A new all-time daily precipitation record for Billings was set on May 24th. These two ...

Flood — Jun 12, 2011

The combination of recent rainfall amounts of 2 to 4 inches across the area and mountain snow melt resulted in rapid water runoff and flooding. As a result, the Musselshell River rose above flood stage from Harlowton to Ryegate, as well as in the towns of Roundup and Musselshell.
