Here’s a look at James Maxwell Clark and the Union Colony, from Caroline Black writing for The Greeley Tribune. From the article:
From 1872-1875, the economy of Greeley was hurting as farmers battled harsh winter storms, drought and grasshoppers. They attempted to learn new forms of crop cultivation that were in contrast with what they had experienced in the humid areas of the eastern United States. Like his neighbors, Clark found farming a terrible struggle, leading him to name his farm “Poverty Flats.”
During Clark’s study of irrigation he became a major contributor to the theory and practice of irrigation in the Greeley area, and the door of prosperity began to open for area farmers. He and [Abner Baker], who later founded Fort Morgan, helped construct ditches between Fort Morgan and Brush, and Clark became director of the No. 2 canal that travels south of Timnath through to north of Greeley, and the Upper and Lower Platte and Beaver Canals near Fort Morgan. He also assisted James P. Maxwell, first Colorado State engineer, in devising plans to measure water for irrigation use among area farmers.
