2023 Track 2 Day 2: Bishop Cafarella

TRACK 2, DAY 2

Belfountain Dam and Headpond Class EA and Construction

ABSTRACT

Credit Valley Conservation (CVC) has owned and operated the Belfountain Conservation Area since 1959. An aesthetic dam and headpond enabled swimming, boating and fishing. Geotechnical investigations determined that the spillway does not meet current Provincial guidelines (LRIA) for structural factors of safety.

CVC considered a broader range of long-term management options for the dam and headpond and engaged WSP to undertake this evaluation in the context of the Conservation Ontario Class EA process. The popular park and study area has significant fisheries, wildlife, cultural heritage and archaeological constraints and opportunities which triggered significant Provincial agency interest and that of the local community.

The team advanced a preferred alternative that meets competing objectives to conserve and/or enhance several natural, cultural and socioeconomic criteria, while also satisfying the diverse set of stakeholders. The preferred alternative included lowering the existing dam spillway to allow construction of a naturalized channel through the existing headpond area.

Beyond the naturalized channel, lands were naturalized and repurposed as recreation and cultural areas. Approved by MECP in 2017, WSP and Matrix undertook detailed design, approvals, tender services and construction administration. Designed in 2020, approved March 2021, pre-qualification and tender in 2021, and construction was July to Dec 2021. Dewatering and sediment control employed fluming.
