On 23 – 24 June of 2017, the upstream Gorrie Dam failed and the Howson Dam was at capacity during an extreme rain event and flood when 175 mm of rain fell in just 7 hours, placing more than 150 property owners at risk and resulting in an estimated $11-million in damages in the Town of Harriston. This severe rain event broke previous records by approximately 40% and was the second highest flow on the North Maitland in the 48 years of record. Fortunately, no one was killed; however, it could have been much worse, as in October of 2015, when a South Carolina flood breached 18 dams, and resulted in 16 deaths.
It has come to ORA’s attention that the Gorrie Dam on the North Maitland River failed as a result of flooding during an extreme rain event on 23 – 24 June 2017, and that Maitland Conservation is considering its options. We understand that no one is more aware of the extremes of a volatile and changing climate than Conservation Authorities, and yours in particular; and we understand the pressure that Conservation Authorities and municipalities are under when communities rally to maintain their coveted mill ponds. However, it is up to all authorities to take a leadership role that places public safety and landscape scale ecological integrity above local individual or group interests.
Drought conditions could place additional stress on riverine ecosystems, while more extreme rainfall will heighten the risk of dam failures (18 dams were breached in a South Carolina flood in October of 2015) with rapid release of high volumes of water. There have also been recent dam failures right here in Ontario – the Gorrie Dam failure last year in Wingham was the most recent, putting more than 150 property owners at risk.
Many individuals and groups embarking on the Part II Order process are new to it, have no legal assistance or background, and are unfamiliar with the terminology and rules; therefore, if we are truly aiming to provide help to the public it is extremely important that clear, succinct and concise instructions be provided in this policy/guidance document.
This document does not go far enough to place CAs in a central role of watershed planning and management, or in working collaboratively with other municipalities and planning authorities. The CAs have a mandate to ensure the conservation, restoration and responsible management of Ontario’s water, as well as the land and natural habitats; however, municipalities have no such mandate and are more development oriented. It is essential that municipalities are not just using this Watershed Planning Guidance purely for municipal land use planning or a stormwater management tool, but that CAs play a central role, and it is used as an integrated watershed planning and management framework.
In September of 2016, the Grand River Conservation Authority (GRCA) received a Feed-in-Tariff Power Procurement Contract from the IESO to sell power to the grid. In June 2017, the GRCA initiated a Class Environmental Assessment to evaluate the construction of a waterpower project, the Parkhill Hydro Generating Station located at the existing Parkhill Dam in the City of Cambridge. If approved and constructed, this waterpower project would have a nameplate capacity of 500 kW. The project is subject to the provisions of the Ontario Waterpower Association “Class Environmental Assessment for Waterpower Projects.” Pursuant to the Class EA, this project is considered to be associated with existing infrastructure.

OTTAWA, Mar. 19, 2018 – Increased federal action to protect and recover American Eel is urgently needed, say the Canadian Wildlife Federation (CWF) and nine other partners in conservation including the Algonquin to Adirondacks Collaborative, the Lanark County Stewardship Council, Nature Québec, Ontario Nature, and the Ontario Rivers Alliance.
