Description: This data is used to provide users with reference information for mapping purposes. This dataset resides in the waterbalance.gdb database.The hydrogeological information presented in the Water Balance Web Application is derived from hydrogeological modelling, and contains inherent uncertainty. The water budget values shown are based on a regional model developed by the Regional Municipality of York with funding from the Ministry of the Environment and Climate Change and the Ministry of Natural Resources and Forestry, and should be used with caution at the site scale. In addition to being scale dependent, the web application is temporally dependent. The water supply information represents 30-year ‘normal’ or average conditions (Oct 1983- Oct 2013), and will generally be different from the water balance parameters observed at any point in time.https://s3-ca-central-1.amazonaws.com/trcaca/app/uploads/2019/10/21120917/DOC_20191021_WHPA-Q_WBGuidance_Ver2.1.pdf
