The Old Merritt Highway (5A) between Kamloops and Merritt is now fully open to traffic.
DriveBC announced at 1:15 p.m. on Friday that the highway at Stump Lake, about 40 kilometres south of Kamloops, has a gravel surface in place that is allowing traffic to flow in both directions.
On May 4, the B.C. Ministry of Transportation and Infrastructure closed the highway due to flooding when Stump Lake spilled its banks. On May 15, the roadway was reopened to single-lane, alternating traffic.
Thompson-Nicola Regional District emergency program co-ordinator Kevin Skrepnek previously told KTW high water and wind in the area created wave action on Stump Lake that pushed debris onto the road at the lake.
Stump Lake flooded in 2017 and 2018. Significant flooding in 2018 was followed by a meeting with representatives from the province, regional district and property owners affected.
“A few options were looked at, in terms of potentially building a dam or doing excavation to let more water out,” Skrepnek said.
“There were three options, one of them being the status quo and the other two were going to be very complicated and expensive options, which would require a lot of regulatory approval from the province and federal government, as well. When we looked at the options in 2018, there was no clear path forward.”
In May of 2018, with flooding rampant across the B.C. Interior, then-TNRD Area M (Nicola Valley North) director Randy Murray told KTW the only way water can leave Stump Lake, aside from evaporation and ground filtration, is if levels rise to clear a dam that is no longer operational.
