Penhold lake water supply to locomotives


Penhold Lake historically served as the water supply for steam locomotives along the CPR line, with water being pumped from the lake into railway water tanks to refill locomotive boilers.[1][2][3]

Water Supply Infrastructure

  • Because steam locomotives required frequent water stops—often every 50 miles—the CPR built water tanks at sidings like Penhold, supplied by local sources including Penhold Lake.[1]
  • Water was pumped from Penhold Lake to nearby storage tanks, which had capacities ranging from several thousand to tens of thousands of gallons depending on the volume of train traffic.[1]
  • These tanks were usually built near the tracks, enabling crews to fill up quickly before continuing their journey.[3][1]

Why Penhold Lake Was Used

  • Water was chosen from Penhold Lake because reliability and proximity to the railway were key criteria for CPR to establish a stop: Penhold Lake provided a consistent supply year-round.[3][1]
  • The quality and hardness of prairie lake water sometimes required treatment, with maintenance crews using softeners to reduce scaling in boilers.[1]

Transition and Legacy

  • With the shift from steam to diesel traction in the mid-20th century, Penhold’s water supply facilities, like many other railway water tanks, became obsolete and were eventually dismantled or repurposed for community use.[2][1]
  • The practice of using Penhold Lake as a water source for locomotives is commemorated locally as part of the region’s railway heritage.[2][3][1]

Penhold Lake’s historic role as a railway water supply is a testament to how natural resources shaped local infrastructure and daily life during the steam era.[2][3][1]
