Marchiori is a privately owned dam located in Huerfano, Colorado, with the primary purpose of irrigation. Completed in 1952, this earth dam stands at a height of 26 feet and has a length of 300 feet, providing a storage capacity of 160 acre-feet. The dam is situated on Bear Creek-TR and is regulated by the Colorado Division of Water Resources, with state permitting, inspection, and enforcement in place.

Although Marchiori has a low hazard potential, it is classified as having a high risk level, indicating the need for careful monitoring and risk management measures. The dam has not been rated for its condition, with the last inspection conducted in November 1993. Despite its age, Marchiori has not undergone any modifications and does not have a spillway, relying on its structural integrity to manage water flow. The surrounding area covers 12 acres with a drainage area of 3 square miles and a maximum discharge capacity of 441 cubic feet per second.

Water resource and climate enthusiasts will be intrigued by Marchiori's historical significance and its role in supporting agricultural activities in the region. The dam's location in a rural area and its reliance on manual inspections highlight the need for ongoing maintenance and monitoring to ensure its continued safety and functionality. As water resources become increasingly important in the face of climate change, understanding the infrastructure like Marchiori will be crucial for effective water management and planning for the future.
