Recommendations.
On Messalonskee Stream, the water quality effects from a municipal treatment facility in Oakland and a combined sewer overflow in Waterville are elevated due to the impoundments downstream of the discharges and due to flow regulation in the upper Belgrade Lakes. Changes in the amount of treatment provided, location of discharge points and flow management will be required to bring this stream into compliance with the standards for Class C.
The Sebasticook River is eutrophic primarily from nonpoint source nutrient contamination but also from several municipal treatment facilities which discharge in the watershed. Increased residence time of the watershed allows for increased algae growth leading to low dissolved oxygen in the impoundments. Several projects are presently ongoing in the watershed to reduce nutrient loading. Changes may also be required in flow management of the impoundments to dissipate algae growth.
The DEP may assess the need to seek modifications of the operation of the Wyman project to bring aquatic life conditions below that dam into compliance with water quality standards. In addition, DEP may assess the need to seek modifications of licensed discharges in Fairfield and downstream and/or modification of the operation of Edwards Dam to bring this segment into compliance with water quality standards.
