April 10, 2024 — A crack discovered in the Panguitch Lake Dam in Utah on Monday, April 9, 2024, has prompted a Level 2 Emergency Situation and concerns about a potential partial breach. The West Panguitch Irrigation and Reservoir Company found the crack, likely caused by high water levels and ice pressure.
The main dam structure is intact, but a 2-5 foot expansion section from the 1930s/40s is compromised. A complete dam breach is unlikely.
Authorities are taking measures to mitigate the situation, including releasing water to lower the lake level, adding support material to the dam, and trenching the ice to relieve pressure. Evacuation plans are in place if a breach does occur, potentially flooding homes and properties in western Panguitch.

Crews have trenched several cuts across the ice which has helped to relieve ice pressure pushing on the dam. They have also added rock to the downstream side to support the dam wall. These measures have helped to change the tilt of the expanded section from 8 degrees to 2 degrees.
Panguitch Lake was originally a large natural lake that has now been expanded by the creation of a 24-foot dam to become a reservoir with a maximum surface area of 1,248 acres. The lake, which drains into the Sevier River is located on the Markagunt Plateau, between Panguitch, Utah and Cedar Breaks National Monument.
