History

The pond was constructed in the early 1960s as a "swimming hole" from an area that had previously been a wetland of three small islands, known as the Bathing Islands, with channels between them in the Rideau River. The pond, which was completely separated from the river, was used for swimming until the pond was infected by bacteria and the spread of

. The provincial health department ordered the pond's swimming facilities closed in 1971. During the 1970s, the pond was used for model yacht regattas.

Naturalization

In the 1990s there was a large-scale community project to naturalize the area. The project, under the leadership of ECOS (the Environment Committee of the Ottawa South Community Association) saw the planting of thousands of trees and shrubs by local residents, the transformation of the hard-pack parking lot into a meadow, the construction of the pedestrian bridge between the park and Carleton University, and numerous other projects. For a number of years the pond area served as the location of Earth Day Ottawa activities. The naturalization project culminated in 2000 with a major federal government Millennium Grant to dredge a fish nursery on the river's edge, develop interpretive materials, and other undertakings.

The restoration project included creating a wetland with shoreline plantings, and habitats for breeding birds, amphibians, turtle nesting beds and basking logs. The culvert allowed fish from the Rideau River to use the pond.
