Another beach, Graham's Grove, was closed in the early-1990s, as a result of poor water quality stemming from the construction of the nearby "Mic Mac Par-clo" (partial clover-leaf), a large interchange connecting Highway 111, Trunk 7, and Route 318, which replaced the rotary previously on the site.

It was originally approximately two meters shallower than its current depth, after being dammed during the construction of the Shubenacadie Canal in the early 19th century.

During improvements for the 1989 Junior World Championships, the top section of the paddling course was dredged to meet depth standards.

The fill was used to expand nearby Graham's Grove Park, and the former access road still remains underwater.

There have been shoreline modifications for recreational beaches, private waterfront, boat docks, and municipal pipelines.
