In anticipation of the upcoming spring freshet, dam owners throughout the province are being urged to safeguard their water supplies and ensure that their dams operate safely during this period of high flows.
With very wet conditions in the Interior, and as a result, higher risks of dam failures, it is important for dam owners to take precautions.
Dam owners are urged to:
- Conduct regular surveillance and monitoring.
- Clear the spillway of any blockages (including temporary flashboards).
- Ensure the low-level outlet is maintained and operational.
- Review and exercise your Dam Emergency Plan.
- Ensure any inflow diversion structures are maintained and operational.
- Ensure that the required signs for dams located on Crown land are in place and in good repair.
- Under certain circumstances, it may be necessary to lower the reservoir to provide additional storage, to reduce downstream flooding.
It’s important to note that dam owners are responsible for the safe operation, and maintenance of their dams, and are liable for any damages that are caused by them.
