As the Nation's principal conservation agency, the Department 

 of the Interior has responsibihty for most of our nationally 

 owned public lands and natural resources. This includes 

 fostering the wisest use of our land and water resources, 

 protecting our fish and wildlife, preserving the environmental 

 and cultural values of our national parks and historical places, 

 and providing for the enjoyment of life through outdoor 

 recreation. The Department assesses our energy and mineral 

 resources and works to assure that their development is in the 

 best interests of all our people. The Department also has a major 

 responsibility for American Indian reservation communities 

 and for people who live in Island Territories under U.S. 

 administration. 



On November 6, 1979, the Bureau of Reclamation was 

 renamed the Water and Power Resources Service in the U.S. 

 Department of the Interior. The new name more closely 

 identifies the agency with its principal functions-supplying 

 water and power.
