Located in Delta, Colorado, Oasis is a privately owned irrigation structure that has been providing vital water resources since its completion in 1906. This Earth dam stands at a height of 22 feet, with a length of 915 feet, and a storage capacity of 105 acre-feet. Situated on the Gunnison River, Oasis plays a crucial role in supporting agricultural activities in the region, with a primary purpose of irrigation.

Despite its historical significance and essential function, Oasis has been deemed to have an unsatisfactory condition as of the last inspection in 2016. With a low hazard potential but a high risk assessment rating, there are concerns surrounding its structural integrity and overall safety. This highlights the importance of ongoing monitoring and maintenance efforts to ensure the continued operation and safety of this water resource infrastructure. Water resource and climate enthusiasts would find Oasis to be a fascinating case study in the intersection of historical infrastructure, water management, and environmental risk assessment.
