Maps and Data

Maine Atlantic Salmon Atlas

The Maine Atlantic Salmon Atlas provides detailed maps of Atlantic salmon spawning and rearing habitat along 16 rivers in Maine. Maps and data contained in the Atlas provide helpful tools for Atlantic salmon researchers and resource managers involved in fish stocking and habitat restoration, as well as federal, state agency and land trust staff and volunteers focusing on habitat protection. Readily retrievable information from the Atlas, combined with technical expertise from Gulf of Maine Coastal Program staff and other partners has been used to identify, prioritize and catalyze habitat restoration and protection opoportunities that support Atlantic salmon recovery.

For specific information on obtaining maps and data identifying spawning and rearing habitat of Atlantic salmon, review the following information:

Habitat information on spawning and rearing habitat for Atlantic salmon is available for all surveyed portions of the following watersheds: Aroostook, Dennys, Ducktrap, East Machias, Kennebec, Machias, Narraguagus, Passagassawakeag, Penobscot, Pleasant, Presumpscot, Saco, St. George, Sheepscot, Tunk and Union River. Habitat data was collected between 1983 and 2005 by field biologists from the Maine Atlantic Salmon Commission and the U.S. Fish and Wildlife Service Maine Fisheries Program Complex. Staff at Gulf of Maine Coastal Program and the Maine Atlantic Salmon Commission developed the habitat data for the completed Atlas.

To view surveyed spawning and rearing habitat and other significant points of interest along specific rivers, go to the Maine Office of GIS maps website, find the “Maine Atlantic Salmon Habitat Atlas Map Series” and select the watershed of interest to you.

You can view the data in pdf format directly from the website, but if you are interested in frequently accessing data for a specific river system, you will want to download the information for quicker access.

If you want more detail than the Atlas provides, and if you have GIS software, you can access metadata and an ESRI ArcView Shapefile. The Shapefile provides information on the year and type of survey, along with the total area of habitat units (runs, riffles, falls and flats and associated spawning habitat) along the surveyed rivers. This data is available from the Maine Office of GIS website catalog as "ashab3."

If you want more detail than the Maine Office of GIS website catalog provides, and if you have GIS software, Gulf of Maine Coastal Program can provide metadata and additional ESRI ArcView Shapefile. The Shapefile provides information on substrate composition, habitat unit dimensions and other variables. Request this Shapefile from:
