Some trail closures for the next couple of months as part of seismic upgrades to the John Hart dam.
BC Hydro is improving the downstream side of the main earthfill dam, and part of that work includes the installation of about 300 steel H-piles to anchor the base of the dam.
The sound from that piling work will exceed safe hearing levels so nearby public trails will be closed for about eight weeks.
When sounds exceed 85 decibels, with extended exposure, it can cause hearing damage. BC Hydro says the sound may slightly exceed that threshold during driving work when pounding in the 17 metre-long steel piles.
The upper trails within the Elk Falls Provincial Park that lead to the Dolphin Pool area will be closed starting today, Mondays to Fridays, through November 4th.
Access to the Elk Falls Suspension Bridge will remain open.
BC Hydro’s Stephen Watson says crews have sound and wildlife monitoring in place and may adjust the closure areas based on the actual sound readings.
The John Hart Dam Seismic Upgrade Project started last summer and will take about six years to complete.
