April 2, 2020 – A previously planned, temporary break in major construction is now underway at the Scotts Mills Dam. This will take place throughout the spring months to account for heavy flows associated with the spring melt, and accommodate DFO’s in-water restrictions. Minor construction activities may take place out of the water during this time.

Contractors have completed both the upstream and downstream cofferdam, which create a dry workspace for the first phase of work. Construction of the first two sluices will begin when major construction work resumes at the site.
