Lake Errock is an unincorporated community in the Fraser Valley region of southwestern British Columbia. Housing exists primarily on the northwestern shore of the same named lake, which lies southwest of Harrison Bay. The locality, on BC Highway 7, is by road about west of Agassiz, east of Vancouver, and east of Mission. First Nations Archaeologically, Lake Errock is the most westerly of the sizable pit-house villages. First Nations reserves lie to the north and south. Name origin The name of Squakum Lake was officially adopted for the lake in 1924, but appeared as Erroch on earlier documentation. The railway siding was called Squakum. In 1940, the designation of the post office as Lake Errock established the community name. In 1974, the lake was likewise officially renamed. European settlement In the late 1880s, Felix Parent was the initial pioneer settler, acquiring an acreage now fronted by the gas station. In the early 1890s, the Ross Ranch, which encompassed the lake, was described as the largest fruit ranch in the lower Province. Arthur Wellington Ross is believed to have headed the syndicate that owned the property. The venture failed and the orchard was abandoned. The Squakum Ranch, at the end of present Malcolm Rd, was a smaller commercial orchard on the banks of the Fraser River. Alex Malcolm bought the property in 1892. In that era, sternwheelers collected milk and cream at the landing. Tom Wilson was the inaugural postmaster 1892–1895. Wilson, the Ross Ranch manager, operated the post office from his home. When the ranch ceased to be viable, the post office also closed that yearend. After World War I, a number of veterans took up small ranches, but most moved on. In the early 1920s, Charles and Miriam Bell, who arrived and farmed the Parent property, were among the few families who remained as permanent residents during the 1930s. In 1937, Alex Malcolm sold his property to the Kilbergs. In 1951, his cremated ashes were scattered upon the Fraser. G. Robert (Bob) Webster established a general store around 1939 and became postmaster when the post office reopened in 1940. The store property was on the west side of the highway at the south end of the lake. While postmaster 1947–1959, Evelyn Dvorack managed the store, gas pumps, and tourist cabins they had built. In the 1960s, Lake Errock became a predominantly residential area of vacation properties when subdivisions were
