Name: Significant Groundwater Recharge Area (SGRA)

Display Field: IntrinsicV

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Tier 3 model did not encompass entire TRSPA, thus this is a combination of (mostly) the Tier 3 SGRA (where recharge rate is greater than 224 mm/yr) and the Tier 1 SGRA (where recharge rate is greater than 150mm/yr) for the area that fell outside of the Tier 3 model (Etobicoke Creek Watershed). SGRA excludes areas that are fully serviced by Lake Ontario.Background:Both the Tier 1 and the Tier 3 analyses used variations of the PRMS modelling code. The Tier 1 study used the PRMS model (Leavesely, et al., 1983) developed by Earthfx Inc. for the TRCA. The Tier 3 study used rates of groundwater recharge estimated with the integrated GSFLOW model (Markstrom et al., 2008) developed by Earthfx for the Tier 3 Water Budget Analysis.
