Johnson Screens Flat Panel Fish Diversion Screens
Profile wire fish screens prevent entrainment, injury, or death of the targeted aquatic species by physically precluding fish from entering a water intake.
Our non-corrosive, stainless steel screens/panels provide an environmentally friendly option for your fish protection/diversion projects. These fish diversion screens are used in dam and river systems to protect fish from hydroelectric turbines and pumps. All fish or water diversion screens can be customized using a variety of wire shapes and rod sizes or additional framing/support to fit your application.
Fish diversion screens are recommended by leading environmental authorities as one of the best options to protect marine life. The system can be designed at low-inflow velocities in relation to the ambient flow past the screen. This minimizes impingement and entrainment of fish and debris.
