Outstanding Stewards of America’s Waters Award

Nominations for the 2022 OSAW Award are closed.

Outstanding Stewards of America’s Waters (OSAW) honors deserving organizations in the hydropower and marine energy industry for projects that exhibit exemplary operational, educational, historical, recreational, or environmental enhancement and stewardship.

Hydropower’s proven track record of providing a domestic source of clean, renewable, and reliable electricity for more than 125 years is no accident. It has taken hard work, perseverance, creativity, innovation, and a collaborative spirit. Today, these same values are also driving a new generation of hydropower projects that harness the power of oceans, tides, man-made conduits and other waterways, in addition to rivers.

OSAW’s History

In 1994, the National Hydropower Association (NHA) created the Hydro Achievement Awards to recognize organizations and projects committed to excellence in the development and operation of hydropower. In 1999, NHA added the Outstanding Stewardship of America’s Rivers (OSAR) Report to profile the best examples of hydropower’s ability to generate clean, renewable, reliable and affordable electricity while protecting the riverine ecosystem.

Beginning in 2007, these two recognition programs were merged to more effectively provide recognition to deserving organizations and to reflect the changing nature of the hydropower industry, particularly the fact that hydropower can be used in various waterways. The new award program is called the Outstanding Stewards of America’s Waters (OSAW).
