The Army Corps of Engineers constructed the Kinzua Dam. They cite the Flood Control Acts of 1936 and 1938 as the permission for construction and estimate the monetary benefits they have provided over the years in avoiding area flood damage as exceeding $1 billion. Statistical information on the construction of the dam and area recreational information is also provided on the site.
