1 is a privately owned irrigation dam located in Niobrara, Wyoming, along the Dolores Draw river. Completed in 1953, this Earth dam stands at a height of 27 feet with a hydraulic height of 22 feet and a structural height of 25 feet. With a storage capacity of 107 acre-feet, the dam primarily serves the purpose of irrigation, supporting agricultural activities in the region.
Despite being classified as having a low hazard potential and fair condition assessment, Dolores No. 1 is subject to state regulation, inspection, and enforcement to ensure its safety and functionality. With a spillway width of 30 feet and an uncontrolled spillway type, the dam is designed to manage potential flooding events. The last inspection in June 2019 revealed moderate risk, prompting the need for ongoing risk management measures to address any potential issues that may arise.
The dam, situated in a picturesque location with a surface area of 8 acres, plays a vital role in water resource management in the area. With Liz Cheney (R) as the Congressional Representative for the region, Dolores No. 1 remains a key infrastructure supporting the agriculture industry in Wyoming. As climate change continues to impact water resources, the maintenance and monitoring of structures like Dolores No. 1 will be crucial to ensure sustainable water management for the future.
