Statement of Significance
Description of Historic Place
The Mallard Lake Dam is an earthen dam, approximately four metres high and 70 metres in length, located in Mallard Lake at the eastern end of a low valley at the north end of Newcastle Island, across the harbour from Nanaimo on Vancouver Island in British Columbia. The historic place consists of the earthen dam, the lake created behind it and the associated wetland.
Heritage Value
The Mallard Lake Dam, Mallard Lake, and the wetland are significant for their engineering, recreational and natural history values.
The dam and lake are located at a point where a low valley at the north end of Newcastle island drained naturally into the ocean via a small stream. At some time after 1890, the earthen dam was constructed at the eastern end of the valley, creating Mallard Lake and the adjacent wetland, the result of which was a supply of fresh water on the island. The impoundment may have been used as a water source for steam generation for the Newcastle coal mine, or to supply fresh water for the herring salteries or the Canadian Pacific Railway (CPR) Steamship resort at the south end of Newcastle Island. Today the lake, dam and wetland are valued as a regional destination for watching birds, beaver and muskrat. It is believed that the beaver and muskrat were first introduced in the 1930s for the benefit of CPR resort visitors.
The dam is valued as a representative of many small-scale engineering and water management endeavours that have been constructed to create freshwater supplies on the Gulf Islands. The use of the lake and dam for wildlife viewing is, however, unique, as the more typical reason for the construction of these small dams was to ensure a supply of potable water.
The dam has additional recreational values, as the top of the headwall has become part of the trail circulation system, connecting the interior Mallard Lake trail to the northern end of the Shoreline Trail. It is currently closed due to instability and erosion of the headwall, an example of nature triumphing over human endeavour.
