About this map

Portneuf Valley serves as a vital corridor for settlement and early industrial water management in 1917, centered around the community of Chesterfield. This era shows a landscape transitioning through major engineering projects, notably the Portneuf and Marsh Valley Irrigation Co Feeder Canal and the newly established Portneuf Reservoir. These irrigation works were essential for supporting the agricultural life of the valley floor, where several rural educational centers like Goech School, Rigby School, and Kelly School served the local ranching families.
