Flood armouring and water pumping capacity to discharge volumes out of Twin Lakes have been added to relieve pressure of the threat of flooding.
The Regional District of Okanagan-Similkameen said Canadian Armed Forces personnel worked into the early hours of Wednesday morning to add sand armouring to structures to reduce the risk of failure as they try to save homes and the valuable water system infrastructure in Twin Lakes.
As a result of the lake pumping, there will be a slight rise in water levels in Sportsmens Bowl and Park Rill water systems in rural Oliver. The additional controlled flow out of Twin Lakes is being monitored by provincial ministry representatives, engineers and hydrologists. The RDOS said crews are also keeping a careful watch on previous mitigation works and creeks through the entire drainage system as they receive the increased water flows.
