Angled screens and louvers have been experimentally evaluated and developed for diverting fish to bypass within cooling water intake structures. Louvers have been shown to be greater than 90% effective in diverting a variety of fish species in both laboratory and prototype studies. Recent studies with angled traveling screens have shown them to be 100% effective in guiding fish to bypasses. Angled screen and fish transportation systems are presently under construction at two large power plants on Lake Ontario.
