Assessment Reports
Ensuring Safe Water
Safe and abundant municipal drinking water is critical to maintain a high quality of life. But how do we know how much is available, how safe it is, and what can threaten it? Assessment Reports look at an entire watershed – both above and below ground – and all interactions with drinking water sources in order to ensure both its quality and quantity.
Assessment Reports were the basis for our region’s Source Protection Plan, drafted by our Source Protection Committee (SPC), which protects drinking water quality and quantity in our watershed. Our region’s Assessment Reports were submitted to the Minister of Environment and Climate Change on July 3, 2014, and given the “green light” on January 26, 2015.
Amendments
- November 15, 2022: Recent amendments to the Township of Oro-Medonte, the Township of Springwater, and the Township of Clearview in the Lake Simcoe, Severn Sound, and Nottawasaga Valley Assessment Reports have been made under Section 34 of Ontario Regulation 287/07.

The amendments reflect the decommissioning of two wells comprising the Goldcrest drinking water system, previously included in the list of water supplies for the Town of Innisfil. Refer to Chapter 10 of the Lake Simcoe Assessment Report and Chapter 13 of the Nottawasaga Valley Assessment Report.
- August 4, 2015: Recent amendments to the City of Barrie chapters in the Lake Simcoe and Nottawasaga Valley Assessment Reports have been made under Section 51(6) of Ontario Regulation 287/07. Amendments reflect changes made to potential threat counts as a result of the SPC’s decision to demote septic systems from significant threat status in the City of Barrie Issues Contributing Area under Technical Rules 115 & 131. This decision only applies to septic systems located outside of areas where the vulnerability scoring is 10. Refer to Chapter 8 in the Lake Simcoe Assessment Report and Chapter 9 in the Nottawasaga Valley Assessment Report.
