WaveEater will withstand non-moving ice pressure. The units have a 1/8” wall thickness and since they are only filled two thirds with water there is room for expansion within the module. Like other floating structures they are susceptible to damage if they are exposed to ice flows. However, there are a number of installations in northern climates where the system has not been removed in the winter, and the units have suffered no damage.
The photos show an installation in Dillon Reservoir west of Denver. Elevation is 9,114 feet, (2778m). Ice thickness is variable, but the photo would indicate at least 12-24” (31-61cm).
