Public Safety Assessment (PSA) and Hazard Potential Classification (HPC) for five (5) dams on the Moira River in downtown Belleville.
These dams are essentially concrete gravity free overflow (spillway) structures with a large weir that is used to control flood flows and to control ice development and ice flows in winter and during the freshet and are located in a densely-populated area.
The study was completed in accordance with the requirements outlined in the Technical Guidelines and Best Management Practices drafted by the Ontario Ministry of Natural Resources and Forestry (MNRF, 2011) and with the Canadian Dam Association (CDA, 2011) Guidelines for Public Safety Around Dams.

The project started in December 2016 and the documents were completed in March 2017.

Public Safety Plan (PSP) for one dam and a Dam Safety Review (DSR), an Emergency Preparedness Plan (EPP) and Operation Maintenance and Surveillance (OMS) for three dams on the Moira River in downtown Belleville. The work was done in accordance with MNRF Guidelines (2011).

These dams are essentially concrete gravity free overflow (spillway) structures with a large weir that is used to control flood flows and to control ice development and ice flows in winter and during the freshet.
Due to client satisfaction, this project was a continuation of the conclusions reached by the previous PSA and HPC project by AGCL for QCA.

The project started in May 2017, is ongoing, and is due to be completed in July 2017.

HPC and Stability Assessment of the water retaining and appurtenant structures of the Backus Mill Dam Reservoir, in accordance with the MNRF Guidelines (2011). A PSA was performed for the dam in accordance with the CDA Guidelines (2011).

The Backus Mill Dam, built in the 1800s (date uncertain), is a composite gravity dam with earthen embankments on either side of a concrete spillway with stop-logs for adjusting water levels. Portions of the embankment at Backus Mill Dam were previously determined to be steep and over steepened with areas of ongoing localized loss of material, and the concrete spillway required rehabilitation. Calculations were prepared for the embankment and concrete spillway stabilization, and construction drawings with embedded technical specifications were also prepared.

The project started in December 2016 and the documents were completed in March 2017.
