vector digital data
Contains data updates through 2016
UPDATED: March 17, 2021 with data through the 2020 survey year.This coverage was developed from field surveys conducted on the mainstem and selected tributaries of the Aroostook, Dennys, Ducktap, East Machias, Kennebec, Machias, Passagassawakeag, Penobscot, Pleasant, Presumpscot, Saco, Sheepscot, St. George, Tunk and Union Rivers in Maine by staff of the Maine Dept. of Marine Resources - Division of Sea Run Fisheries and Habitat. These surveys were conducted to identify important Atlantic salmon habitat including spawning and rearing areas. The majority of the survey data was collected using Trimble Pro, Pro-XL and GeoExplorer3 receivers and survey files were differentially corrected to provide 2-5 meter accuracy. Surveys for some reaches were collected with minimal or no GPS control points and the attributes were overlaid on a stream centerline created using either a GPS-acquired line, a line derived from MEGIS/USGS 1:24,000 hydrography data, or a line drawn as a centerline based on MEGIS digital orthophotography. The dataset includes information on habitat categories and areas, and an indication of spawning and rearing potential. This data is referred to as Level 3, or detailed habitat survey data, to be contrasted with the Level 2 habitat data which contains the most detailed data for individual habitat units.

Spawning
The survey crew's assessment that usable spawning habitat is present. The primary characteristic considered is substrate. Flows and depths are considered secondarily. The survey crew assigns a percentage of the habitat unit that is suitable for spawning, or identifies one or more limited spawning patches.
USFWS, MeSRFH
Yes
The entire habitat unit is considered to have spawning potential though it may be limited spatially or qualitatively. Potential spawning area within a flatwater (Habcat = Flat) unit that constitutes more than 30 % of the unit area, mean the entire unit is coded as potential spawning habitat. Refer to the SpawnArea field to verify the amount of spawning habitat in a particular habitat unit.
Limited
The habitat unit is considered to have limited spawning potential. If the potential spawning area in a flatwater (HabCat = Flat) unit constitutes less than 30 % of the unit area, the entire unit is coded as limited spawning habitat. Refer to the SpawnArea field to verify the amount of spawning habitat in a particular habitat unit.
No
No spawning potential was identified for this area in the field surveys of record.

SpawnArea
Area within the habitat unit in square meters that is considered suitable for spawning. Defined by one of two methods: Spawning Patch Dimensions - if a single, small, discrete portion of the habitat unit was considered potentially useful for spawning, the dimensions of the patch were recorded (units coded as Habcat = "Flat" can be coded as spawning units); or Proportion of Habitat Unit - if multiple spawning patches were present, or a single, large spawning patch was identified such that obtaining dimensions of the patch was difficult, estimation of the proportion of the habitat unit potentially useful for spawning was made and applied to Area to yield SpawnArea.
