ARA polygon segments may represent a portion of a water body or an entire water body (such as a lake, river or stream). Attributes for each location may include: * physical characteristics such as water temperature and depth * fish species observed The ARA data classes are the authoritative source for generic spatial data related to fish species in Ontario. The data may be used for: * forest and fisheries management planning * municipal planning * natural heritage and other land use planning * issuing work permits under the Public Lands Act, 1990 * issuing licenses under the Fish and Wildlife Conservation Act, 1997 * fulfilling public information requests There are additional sensitive data related to provincially tracked species and species at risk that are not available as part of this open data package.
