Columbia River irrigation and rail expansion define this reach of the river during the mid-1910s. Small river settlements like Wahluke and Allard sit along the banks, supported by the infrastructure of the Chicago Milwaukee and St Paul railroad and the Hanford Branch. The presence of the Pumping Plant and the Hanford Ditch highlights the early 20th-century efforts to reclaim this arid landscape for agriculture.
