Black and Amber on the Columbia Basin Project

The Columbia Basin Project is one of the largest federal irrigation undertakings in American history. Its spine is Grand Coulee Dam on the Columbia River in eastern Washington, completed in 1942 after nine years of construction — at the time, the largest concrete structure in the world. The dam's pumping plants lift water from Lake Roosevelt into Banks Lake, a 27-mile equalizing reservoir occupying the old dry bed of the Grand Coulee itself, and from there over 300 miles of main canals distribute it across what had been semi-arid shrub-steppe. Congress authorized the irrigation component in 1943; the first water reached farms in 1948.

By the early 1970s — the most likely date for this brochure, based on the graphic design — roughly 500,000 acres were under irrigation, producing potatoes, wheat, alfalfa, and corn on land that had supported almost no row-crop agriculture before the dam. The project's promotional literature was widely distributed at Bureau visitor centers, congressional offices, and public hearings accompanying each new phase of canal construction.

The design carries the visual language of the International Typographic Style — informally "Swiss Style" — that arrived in American federal publishing during the late 1960s. Heavy sans-serif type in white on black, a narrow geometric accent stripe, and full-bleed black-and-white photography were hallmarks of how agencies like the Bureau and the National Park Service modernized their identities in this period. The amber stripe and black-panel treatment appeared across Bureau brochures for multiple western projects, suggesting a shared template applied region by region.

• The two-panel layout — series title on one face, project name on the other — is consistent with a Bureau publishing convention where a single cover template was adapted for the Central Valley Project, the Bonneville Project, and others across seventeen western states.
• The photograph's extreme contrast — white water against near-black rock — was a deliberate choice well-suited to the era's federal print budgets; adding a color halftone plate on uncoated stock would have significantly raised unit costs with diminishing visual return.
