Oligarchy #1, also known as Burch Lake, is a privately owned irrigation dam located in Boulder, Colorado. Built in 1889, this earth dam stands at a height of 29 feet and has a storage capacity of 2161 acre-feet, primarily used for irrigation purposes. The dam is situated on the St. Vrain Creek-OS and is regulated by the Colorado Division of Water Resources, with inspections and enforcement measures in place to ensure its safety and functionality.

With a spillway width of 167 feet and a maximum discharge of 1580 cubic feet per second, Oligarchy #1 poses a significant hazard potential but has been assessed as satisfactory in condition as of May 2020. The dam underwent modifications in 1988 for its foundation and in 2004 for its structural integrity. Despite its moderate risk assessment, the dam's risk management measures and emergency action plan readiness are not explicitly outlined in the available data. Owned and operated privately, this historic irrigation structure plays a crucial role in water resource management in the Longmont area.

For water resource and climate enthusiasts, Oligarchy #1 serves as a fascinating example of a privately owned irrigation dam with a long history of providing essential water storage for agricultural purposes. Its design and construction details, as well as its regulatory oversight and risk assessment, offer valuable insights into the intersection of water infrastructure management and environmental stewardship. As discussions around water scarcity and climate change continue to shape policy and practice, understanding the complexities of dams like Oligarchy #1 becomes increasingly important in ensuring sustainable water resource management for future generations.
