The fish hatchery at Bon Accord (1886)

A satellite view of the Port Mann area, with the deep gorge of Bon Accord Creek winding its way 328 feet down to the Fraser River. The natural path of the creek has been altered to flow to the right of the Port Mann Bridge using an open cement culvert. For thirty years the creek supplied water to the locomotive water tank and Port Mann townsite built by the Canadian Northern Railway. With the number of smaller creeks that flow down from the uplands here -- now culverted and a trickle of their former selves -- the NWSR must have used many small timber trestles along this section of the Fraser.
