Lake Ontario Tributaries: 2009-2010 Field Data Report

Due to the E.O. Honoring the American History of the Great Lakes and Renaming Lake Ontario as Lake America, EPA is updating all references to Lake Ontario to reflect its renaming to Lake America. We are working rapidly to update this.

In 2002, EPA began a program to regularly monitor U.S. tributaries to Lake Ontario for the critical pollutants. This report provides program results from 2009-2010, and identifies changes in the monitoring program from prior years.
