Why We Monitor

There is little actual data that exists on the water quality of the Saco, Ossipee, and Little Ossipee rivers. Regular but infrequent testing by the state of Maine indicated that water quality has improved. The Maine Department of Environmental Protection (DEP) tests the water in the Saco River at six separate locations once every five years. Their testing regime is physical — unlike the Saco River Corridor Commission testing, which is chemical in nature.

The Maine DEP looks for the presence of aquatic insects that can be used as “indicator species” for water quality. Other isolated and periodic testing of discrete areas along the rivers over the years was carried out primarily by school groups without a commitment to long-term data collection. Because long-term background information is not available, it is difficult to determine the current water quality in the river. It is also difficult to determine if current land use management strategies and regulations remain effective.

The hope for this program is to collect and store data for use by towns in the corridor and for the state of Maine and to help us refine and/or reform our regulations to meet the current needs of the rivers and citizens in the corridor. Having the data allows us to create a picture of the river systems. Over time, this picture will emerge to show trends in water quality. Identification of problem areas along the river and a more informed decision-making process will be the direct outcome of this program.
