US Environmental Protection Agency – “It is perceived that advancement of turbine technology which could reduce fish mortality resulting from turbine passage to less than 2%, in comparison with turbine -passage mortalities of 5 to 10% for the best existing turbines and 30% or greater for some turbines, would help reverse the decline in hydro generation”.
US Environmental Protection Agency – “Improved compliance with water quality standards: Advanced turbine technology which would maintain a downstream dissolved oxygen level of at least 6 mg/L, ensuring compliance with the latest water quality standards, would lead to a reverse in the decline of small hydro implementation”.
