About this map

Longmont and the surrounding agricultural landscape are defined by an intricate network of irrigation systems and reservoirs that support the communities along the Boulder and Weld county line. The map illustrates how historical water rights have shaped this region, featuring numerous named canals such as the Highland Ditch, Oligarchy Ditch, and Rough and Ready Ditch. These waterways feed significant reservoirs including Calkins and Terry Lake, which stand as critical infrastructure for the eastern plains.

Genealogists and local historians can locate established landmarks like the Mountain View and Burlington cemeteries, or the Boulder County Courts. The transition from the urban density of Longmont to the outlying settlements of Mead, Firestone, and Frederick reveals the 21st-century growth pattern of the Colorado Front Range, where residential expansion increasingly borders established landmarks like Standley Hill and the riparian corridor of Saint Vrain Creek.
