Cobbossee Stream in Gardiner

COBBOSSEE STREAM

February 8, 2023

Cobbossee Stream Powered Gardiner’s past…now let’s give the stream a future.

Cobbosseecontee Stream runs through 15 towns and flows through the City of Gardiner where it meets the Kennebec River. The lakes, streams and ponds of the Cobbosseecontee watershed were once home to at least seven species of diadromous fish. Long dammed, the 240 acres of the Cobbossee Stream watershed represent valuable but inaccessible habitat for alewives and blueback herring.

Maine Rivers is focused on supporting efforts for safe, timely and effective fish passage to bring back the historic productivity of native fisheries while maintaining progress made over many decades to eliminate sources of water quality degradation.

Upstream is a local non-profit working to restore sea-run fish passage and ecological health to Cobbossee Stream.
