In 1969, the Cuyahoga River caught fire, bringing more negative national publicity to Cleveland and its polluted waterways. Even though pollution in Lake Erie was a regional problem, Cleveland bore the brunt of the negative publicity.
The burning river and the "dead" lake were major impetuses for the Federal government to step in and deal with water pollution in Cleveland and across the nation. In 1972, Congress passed the Clean Water Act, a measure that tightened regulations on industrial dumping. That same year, the United States and Canada signed the Great Lakes Water Quality Agreement in an attempt to lower the amount of pollutants entering the Great Lakes.
