Significant avalanche activity during the winter of 2018/19 threatened to breach the remains of the historic Hidden Treasure Dam and damage the town downstream. Harrison Western developed and executed an emergency blasting plan to remove the lower section of the dam in a controlled manner from a crane-supported work deck in order to allow additional flow and debris to pass before spring runoff. The town was subsequently spared from damage.
