Frazil Net System

Frazil ice is the collection of loose, randomly oriented ice crystals that can form in rivers, lakes and oceans.

Barry designs netting solutions for the retention and accumulation of an ice cover which will reduce the likelihood of ice jams on urban rivers. During the frost period, these floating net systems allow the accumulation of suspended frazil under an iced cover in places where the current normally does not permit it. By using a netting system upstream from water intake structures such as hydroelectric and water treatment plants, the frazil ice can be accumulated in a centralized area, minimizing the loss of production caused when frazil enters the dams.
