About this file

These engineering drawings detail concrete drop structures for the San Juan-Chama Project in Colorado and New Mexico, specifically focusing on Willow Creek Channelization. The technical drawings, prepared by the United States Department of the Interior Bureau of Reclamation in April 1967, provide comprehensive plans, sections, and details for two concrete drop structures located at Station 1565+00 (Azotea Creek) and Stations 1702+75 and 1831+17 (Willow Creek). The drawings include precise measurements, reinforcement specifications, and structural details such as half plans, longitudinal sections, and cross-sections, with notes specifying construction requirements like concrete compressive strength, reinforcement placement, and edge chamfering. The structures appear to be designed for water management and erosion control, featuring sloped slabs, baffle blocks, riprap, and gravel bedding.
