Contractors working on the Park Lake Dam project will use controlled blasting Monday to break apart roughly 25 large boulders — some larger than a bulldozer — as removal work continues at the site. The Helena-Lewis and Clark National Forest posted the update Friday, noting that while the area remains closed to the public, residents in nearby parts of Jefferson County may hear loud noises during the work.
The blasting is part of ongoing dam-related work that the forest service says continues to progress. Park Lake, located in Jefferson County, has been the subject of extended dam work involving heavy equipment and contractor crews. No timeline for reopening the area to the public was included in Friday's update.
Residents in the surrounding area who hear the blasts Monday should not be alarmed — the forest service characterized the noise as expected and part of the planned scope of work. The Helena-Lewis and Clark National Forest has been posting regular updates on the project through its social media channels.
