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:
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.
