Description du lieu patrimonial
The Second Lake Dam is situated underneath the travelled surface of Millstream Lake Road on Section 20, where the road crosses the outlet from Second Lake. The presence of the dam from above is largely imperceptible, but it can be observed from below on the downstream side. The dam, situated between two rock outcrops, consists of a concrete wall and a single buttress perpendicular to the wall.
Valeur patrimoniale
The Second Lake Dam is valued as the oldest recorded dam site in the District of Highlands. Other smaller dams were constructed at various places in the Millstream watershed (i.e., First Lake, Matson Lake, and Mary Lake) mostly during the 1940s and 1950s. The original Second Lake Dam, however, was constructed much earlier and is noted in a pre-emption land survey document from 1889. The dam was described in an 1890 land transfer document for section 18 that included Second and Third Lakes. It specified the vendors, who also owned Section 20, must maintain the Second Lake dam "as will ensure the water at and along the division line of the lands known as section 18 and 20 being of not less than 3 feet."
The dam structure is valued for providing a tangible link to a past recreational culture and the aesthetic values brought by some early Highlands land owners. Water licenses associated with these dams often indicate they were constructed for "land improvement" purposes. This is in contrast to engineering efforts like the Fork Lake ditch, which had strictly agrarian purposes. However, it is also valued for a tangible link to agricultural use as well. It is suspected that later improvements to the structure were made to increase storage above the dam, to allow agricultural use of a wetland below Second Lake on Section 20. This may have also involved the construction of a diversion, still in evidence today, to carry water in a more direct route toward First Lake.
Originally a wooden bridge spanned Millstream Lake Road above the dam, allowing overflow from Second Lake underneath. At some point in the late 1960s or early 1970s the wooden bridge was replaced by a concrete culvert that now sits on top of the old dam flanked by stone walls. The existing concrete dam structure was probably constructed in a slightly later period to simplify maintenance, but likely incorporated parts of the earlier dam.
