1966 Map of Mile High Lakes

About this map

The Barr Lake State Park area in Adams County reflects a landscape defined by significant water management and the early footprint of regional infrastructure. While much of the eastern portion of the map is dominated by the emerging contours of the Denver International Airport, the northwestern corner preserves a cluster of essential water bodies known as the Mile High Lakes. These include Bowles Reservoir No 2, Calhoun Reservoir, and Meeks Res No 1, which supported local agriculture and recreation. Cultural markers of the rural community are visible through the Green Valley Grange Hall and the Patton Ranch. The southern terrain is etched by Third Grass Valley Creek, highlighting the natural drainage patterns that coexist with more modern additions like the Radio Tower and Landing Strip.
