Eagle Island sits at the heart of a complex hydrological landscape where the Boise River splits and intertwines with an extensive network of irrigation infrastructure. This survey, updated with late-1970s urban revisions, documents the transition of the Ada County countryside as the communities of Eagle and Garden City began to expand. The map is particularly rich in water-management history, featuring numerous named man-made waterways like the Thurman Mill Canal, Warm Springs Canal, and the Capitol View Canal, which were essential for transforming the dry valley into productive land.
