This spatial dataset represents the locations of aquatic resource area (ARA) polygon segments derived from corresponding polygon features in the Ontario Hydro Network. 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](https://www.ontario.ca/laws/statute/90p43), 1990 * issuing licenses under the [Fish and Wildlife Conservation Act](https://www.ontario.ca/laws/statute/97f41), 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. Distribution of sensitive species data is approved on a need-to-know basis. Requests should be sent to [geospatial@ontario.ca](mailto:geospatial@ontario.ca).

Watercourses are line features - natural or manmade - that represent the location of flowing surface water. This product requires the use of GIS software. *[GIS]: geographic information system

This historic dataset delineates valley segments based on a number of different natural features. The data applies to valley segments on the Ontario side of the Great Lakes. ALIS has also been incorporated into the [Aquatic Ecosystem Classification: Great Lakes Basin and Wetlands Data Class](/dataset/aquatic-ecosystems-in-the-great-lakes-basin) and the Great Lakes Conservation Blueprint for Aquatic Biodiversity datasets. *[ALIS]: Aquatic Landscape Inventory System We are no longer updating this data. It is best suited for historical research and analysis.

This dataset series contains line, point & polygon features delineating hydrology. It is a combination of a number of data sets that are a part of Vicmap Hydro. Datasets in the series are listed below. See their metadata entries for more detailed metadata. Features include (but are not limited to); rivers, lakes, dams, reservoirs, marinas, and desalination plants. Watercourse Network 1:25,000 - Vicmap Hydro (HY_WATERCOURSE); Water Point 1:25,000 - Vicmap Hydro (HY_WATER_POINT); Water Area (polygon) 1:25,000 - Vicmap Hydro (HY_WATER_AREA_POLYGON): Water Area Fuzzy (polygon) - Vicmap Hydro (HY_WATER_AREA_FUZZY): Water Structure Point 1:25,000 - Vicmap Hydro (HY_WATER_STRUCT_POINT); Water Structure Line 1:25,000 - Vicmap Hydro (HY_WATER_STRUCT_LINE); Water Structure Area (polygon) 1:25,000 - Vicmap Hydro (HY_WATER_STRUCT_AREA_POLYGON); Navigation Line 1:25,000 - Vicmap Hydro (HY_NAVIGATION_LINE); Navigation Point 1:25,000 - Vicmap Hydro (HY_NAVIGATION_POINT);

The ACT Water Featured Lines data set contains polyline information representing an area of land that is or may be covered in water, either intermittently or constantly, temporarily or permanently. The Water Features data set was digitised in 1995 from 1:10,000 Plan Series, 1:2,500 Cadastre, 1:2,500 Detail, 1:1,000 Detail and traced from Topobase.
