There was ferocious rivalry between the railway companies around 1910. The two companies were the Canadian Northern Railway (which later became the Canadian National Railway) and the Canadian Pacific Railway. They had their construction crews competing to build across the West. While the CNR crew was working west from Maryfield toward Radville and Moose Jaw the CPR was pushing from Estevan toward Axford on their Weyburn-Lethbridge line. The CNR was victorious and the CPR was cut off at Neptune. The CPR survey called for a line that would have crossed what is now the northern part of the Larsen Dam and on toward the northwest.
