Aquatic Habitat Inventory Water Chemistry Data

The Aquatic Habitat Inventory contains lake, river and stream survey data collected from the 1950s to the 1990s. These surveys were conducted to acquire basic knowledge of the chemical, physical and biological characteristics of Ontario’s lakes, rivers, and streams to aid in watershed planning, aquatic habitat conservation and fisheries management.

Data Collection Processing

The official name of the lake, river, or stream approved by the Ontario Geographic Names Board is used as the Monitoring Location Name. Where there is no official name, the unofficial name is used and labeled as such (E.g., Patricia Lake (Unofficial Name)).

For some waterbodies there were monitoring site-specific coordinates provided. To account for any method inaccuracies or transcribing errors, a horizontal accuracy measure of 500 m is assigned to these site-specific location coordinates. In all other cases the monitoring location is indicated by general waterbody coordinates, locating either the mouth of a stream or a central point in a lake. A horizontal accuracy of 2000 m is assigned to these waterbody coordinates to account for the formerly mentioned method inaccuracies as well as the fact there may be multiple sampling sites within the lake or stream.
