MakingWaves - Celebrate Water Week

Five Decades of Water Restoration and Protection

DEC's Division of Water invites you to celebrate Water Week with us as we highlight some of the milestones in each of the five decades since the first Earth Day in 1970.

Today’s topic: Milestones of the 1970s

Did you know?

  • When the first Earth Day was held in 1970, many factories and cities were routinely discharging untreated waste waters directly to New York’s lakes, rivers and streams. Many waters were unusable, and fish and wildlife were being harmed. Today, visibly cleaner water and revived fish populations draw growing numbers of boaters, swimmers and anglers.
  • In 1972, the federal government passed the Clean Water Act, which delegated new responsibilities to DEC, including wastewater discharge permitting. That same year, New York began allocating billions of dollars through DEC’s Construction Grants Program to build an advanced network of sewage treatment facilities to reduce raw sewage flowing into rivers, lakes, and streams.
  • New York passed the Tidal Wetlands Act in 1973 and the Freshwater Wetlands Act in 1975 providing important protection for wetlands, which play a vital role in surface and groundwater quality, flood and erosion control, and fish and wildlife habitat.

Answer: In 1972, the U.S. signed the Great Lakes Water Quality Agreement with Canada to begin cleanup of the Great Lakes. About 80 percent of New York's fresh surface water, over 700 miles of shoreline, and 40 percent of New York's land area expanding over 33 counties are contained in the drainage basins of Lake Ontario, Lake Erie, and the St. Lawrence River.
