2022 Map of Highline Lake

About this map

Highline Lake and the Government Highline Canal dominate the southern landscape of this portion of the Grand Valley, illustrating the complex water management systems essential to agriculture in the Colorado high desert. The small settlement area of Mack Mesa sits just south of the Mack Mesa Airport, where the terrain transitions from irrigated lowlands to the dissected uplands of Demaree Canyon and Camp Gulch. The map reveals a dense network of recreational paths and local access roads, including the Greasewood Flats Trl and East Bluffs Loop Trl, which navigate the mesas and bluffs. Drainage patterns are defined by numerous seasonal waterways like Salt Cr, Reed Wash, and Coyote Wash, which flow southward toward the valley floor, carving out the rugged topography that characterizes the border between Garfield and Mesa counties.
