Assembling habitat data layers for determining fish habitat suitability in areas impacted by water level change = Assemblage des couches des bases de données sur l’habitat pour déterminer la qualité de...: Fs97-6/3234E-PDF

"From 2001 to 2005, a five year study was undertaken by the International Joint Commission (IJC) to assess and evaluate water level regulation of the Lake Ontario–St. Lawrence River system. Thus, the nearshore habitat databases for Lake Ontario and the Upper St. Lawrence River was created to provide a structural basis to assess fish habitat suitability, supply and subsequent population responses to changes in water level regulation and climate. The databases also provided a valuable foundation for a broader scope of research and ecosystem assessments in Lake Ontario and the Upper St. Lawrence River. A Geographic Information System (GIS) was the framework in which to store, organize and model the spatial data. This report discusses the GIS data layers that were developed and loaded into the habitat databases, including wetland and shoreline segments, elevation profiles, substrate, fetch (for Lake Ontario) or velocity (for the St. Lawrence River), submerged aquatic vegetation, emergent vegetation and temperature zones"--Abstract, p.
