About this map

The South Platte River and a complex network of agricultural waterways, including the Bull Canal and Brantner Ditch, define the landscape of Adams County in this mid-1960s study. This era captures the rapid southward expansion of Northglenn and Thornton, where new subdivisions are shown encroaching upon long-established irrigation infrastructure. Traditional farming landmarks like the Riverdale Grange Hall and Wesley Chapel Cem stand in contrast to the emerging suburban grid.

Water management is the central theme, as the map records dozens of small impoundments such as Lake Erie, German Res No 2, and the Eastlake Res No 1 through Eastlake Res No 3 series. These reservoirs, often named for local families or nearby settlements like Eastlake, supported the transition from rural prairie to an industrial and residential hub. The Union Pacific rail line and numerous gravel pits further illustrate the region's mid-century economic development.
