In 1965, Governor James A. Rhodes of Ohio requested an interstate enforcement conference for representatives of all the states within the Lake Erie watershed (Indiana, Michigan, New York, Ohio, and Pennsylvania) and the federal government. Lake Erie had become so polluted that public indignation over its condition had reached Rhodes at the statehouse. A Cleveland automobile dealer named David Blaushild had instituted a petition campaign called Save Lake Erie that resulted in more than one million signatures. In April, 1965, Blaushild turned the petitions over to Governor Rhodes. In turn, Rhodes sent them to John W. Gardner, U.S. secretary of health, education, and welfare (HEW), with a request for the interstate enforcement conference. The conference was held in Cleveland, Ohio, in August, 1965.
