The mission of Friends of Sebago Lake (FOSL) is to promote an understanding of the interconnected harmful impacts of unnatural freshwater flows by dam regulation and to advocate for the restoration of natural freshwater seasonal water flows from inland waters to the seas.


FOSL’s mission includes the re-unification of fragmented freshwater ecosystems caused by dams impassable to fish. FOSL works for requirements that all dams in Maine have safe and effective fish passage for the full restoration of the historical range of Maine’s diadromous fishes.

We Pay Attention

To serve as a watchdog over those who regulate the flow of freshwater for their pleasure in their adherence to the laws of the Clean Water Act and State and Federal dam license requirements.

In The Name of Science

Promote the need for scientific study of the impacts of unnatural freshwater flow on the water quality and ecosystems of Sebago Lake and other Maine lakes and their water continuums all the way to the Gulf of Maine.

Friendly Restoration

Require the restoration of more natural seasonal cycles of freshwater flow in our lakes and rivers.

Fight For The Fish

Fight for the restoration of access and safe passage of diadromous fish to Sebago Lake and all Maine river watersheds.

From Here to the Sea

Advocate for and support scientific study of the relationship of unnatural freshwater flow on nutrient flux changes impacting coastal phytoplankton populations, coastal ecosystems, ocean acidity, and climate change
