This is a water temperature dataset collected from 2001 to 2019 throughout TRCA watersheds as part of the Regional Watershed Monitoring Program (RWMP). Water temperature data is recorded in degrees Celcius, once every 15 to 30 minutes through loggers. Data is logged continuously throughout three seasons (spring, summer, fall) although some record year-round. Where possible, temperatures were obtained at the same Regional Watershed Monitoring Program (RWMP) sites where fish and benthic community sampling also occurred. There are 150 RWMP monitoring sites across the TRCA's nine watersheds. Water temperature data is recorded and various locations on a three-year cycle.

TRCA Climate Change Projections under RCP8.5 and RCP4.5 (1971-2100) These datasets represent future climate change projections for TRCA. The summary information can be used by various audiences to better understand the climate trends expected to be seen within TRCA by the end of the century. It is also anticipated that the data will be used to inform various adaptation initiatives across the TRCA jurisdiction. "For the RCP8.5 tabs and the TRCA Baseline tab, Column A represents the climate parameters. Columns C-R represent the individual climate models. Column S is the overall ensemble average of all the climate models. Columns T and U represent the 10th and 90th Percentiles respectively.

Flood Vulnerable Cluster Study Results Currently defined as Flood Vulnerable Areas (FVAs) in TRCA’s Living City Policies, Flood Vulnerable Clusters (FVCs) are sub-areas within the Regulatory storm flood plain that contain multiple existing structures and/or roads for which a single, comprehensive flood remediation approach may be viable. These FVCs include Special Policy Areas (SPAs), as well as historical flood damage centres. For details about SPAs, please refer to TRCA’s Living City Policies. The FVCs within TRCA’s jurisdiction are illustrated on a map located in TRCA’s 2019 Flood Contingency Plan. Note that a FVC boundary is a general radius that includes a concentration of structures and roads within the flood plain. Thus, the FVCs conceptually illustrate these particular flood risk areas at a broader scale.

This dataset contains the species fish caught using boat electrofishing along the TRCA Lake Ontario shoreline from 2000 to 2018. The fish are monitored for a variety of reasons including routine long-term monitoring for the Remedial Action Plan, pre/post construction monitoring, Asian Carp surveillance. Standardized boat electrofishing sampling usually occurs for 1000 seconds (effort) although there are often shorter/longer sampling times depending on the reason for sampling. The first 20 fish of each species are individually measured and weighed before they are put back into the water. The remaining fish for each species are measured together in bulk. The "bulked" fish are listed as individuals with an average length and weight (e.g. 27 Emerald Shiner weighed 36 grams; therefore, there would be 27 individual Emerald Shiners listed that each weighed 1.33 g).
Stream gauge data from TRCA real time and manual monitoring networks. Data represents preceding 15 minute average discharge (flow) in m3/second. Each file contains full period of record of published data. Files are updated annually.
