This dataset includes two folders of spatial data associated with the Trent River. The folder Trent_River includes five files: 1) The portion of the Ontario Integrated Hydrology Dataset Enchanced Watercouse in the river watershed, 2) the location of the study sites, 3) the delineated valley segments on the river mainstem, 4) the valley segment boundary locations, and 5) the watershed outline boundary. The folder Trent_SiteCAT includes the upstream catchment area for each study site.

This dataset includes information about valley segment and catchment summaries, valley characteristics, instream habitat, and fish for valley segments, sites, and transects along four river mainstems in Ontario, Canada. Moving west to east, the rivers include the Grand River which ends in Lake Erie at Port Maitland, the Ganaraska River which ends in Lake Ontario at Port Hope, the Trent River which ends in the Bay of Quinte at Trenton, and the Petawawa River which ends in the Ottawa River at Petawawa. These rivers vary in natural character, anthropogenic development, and fish assemblages. Riverine sites along the mainstems of all four rivers included a total of one hundred and twelve sites. Sampling on the Grand, Trent, and Petawawa Rivers focused on non-wadeable lower river mainstems, whereas all sites on the Ganaraska River mainstem were wadeable and incorporated a wider range of stream sizes. Sites were sampled between 1997 and 2001, with many sites sampled in multiple years. The study design for the Grand, Trent, and Petawawa Rivers include a hierarchical design where data collection was nested at three spatial scales -- shoreline and channel transect data are nested within sites, and sites are nested within valley segments. In the Ganaraska River, data collection was by site and nested within valley segments. A complementary set of shapefiles for each river supports these tabular data and provides items needed to map watersheds, valley segments, and sites, and to calculate additional variables for sites and site catchments. The metadata specific to these spatial data is associated with the shapefiles and is not described here.

This dataset is the result of international collaborative efforts by the United States Geological Survey, the United States Fish and Wildlife Service, the New York State Department of Environmental Conservation, the Ontario Ministry of Natural Resources and Forestry, and the Canadian Department of Fisheries and Oceans. These data provide substrate information along the shoreline of Lake Ontario between 3 and 30 meters in depth. We used drop camera videos to classify substrates with the goal to quantify the amount of quality habitat that could potentially be used for Lake Trout (Salvelinus namaycush) spawning and egg incubation. The videos described within this data release are in zipped files, organized by the collecting agency.
