What is the LAMP?

Under the Great Lakes Water Quality Agreement, the governments of Canada and the United States agreed to restore and maintain the chemical, physical, and biological integrity of the waters of the Great Lakes Basin Ecosystem. This is accomplished in part through the development and implementation of binational Lakewide Management Plans (LaMPs) for each lake. Lake Erie LaMP participants have identified ecosystem goals and objectives and assessed the state of lake. Through the development of issue related strategies, the LaMP will identify actions required to restore and protect the lake and evaluate the effectiveness of those actions. The Lake Erie LaMP is coordinated by a committee of water quality natural resource managers from both Canada and the United States, with participation from federal, provincial, state and local governments that have a role in implementation.

About one-third of the total population of the Great Lakes basin resides within the Lake Erie watershed. In total, approximately twelve million people live in the watershed, including seventeen metropolitan areas with more than 50,000 residents. The lake provides drinking water for about eleven million of these inhabitants. The general trend over the past ten years has been population growth in the urban areas, while the population in rural areas has been decreasing.

During the 1960s water quality issues in the Great Lakes first became a concern to the general public. Lake Erie was perceived to be "dying" as excessive phosphorus entering the lake resulting in eutrophic conditions. By the late 1960s, Canadian and American regulatory agencies were in agreement that limiting phosphorus loads was the key to controlling excessive algal growth and that a coordinated lakewide approach was necessary to deal with the phosphorus issue. Open lake phosphorus concentrations declined due to the joint efforts made. These controls represented an unprecedented success in producing environmental results through international cooperation.

In 1987 the governments of Canada and the United States made a commitment, as part of the Great Lakes Water Quality Agreement (GLWQA), to develop a Lakewide Management Plan for the Great Lakes. The Lakewide Management Plan (LaMP) for Lake Erie is coordinated by federal, state and provincial government agencies in the two countries. Under the guidance of these agencies, the LaMP unites a network of stakeholders in actions to restore and protect the Lake Erie ecosystem. The LaMP provides an opportunity to link their efforts - working towards a common goal - restoring Lake Erie for future generations.
