Descriptive data for the 11 facilities granted continued hydropower production (conditional on meeting modern environmental standards): name of the facility, requirements concerning type of guidance, maximum angle of rack (in cases where the type of guidance was an alfa or beta rack), maximum gap width of rack (in cases where the type of guidance was an inclined or angled rack), amount of water discharge through bypass, eel ramps (yes/no), type of fishway, required slope of fishway, flow in fishway, minimum flow, restriction against hydropeaking (No peaking), and requirements to change turbine discharge at a slow rate (Reduced rate). Missing information in the court decisions is denoted not provided (NP). Note that Kaserna is a regulation dam and not a hydropower facility (hence, water flow and effect are not applicable (NA) at this site.
