Pissolio No. 1 is a historic earth dam located in Weston County, Wyoming, with a primary purpose of irrigation. Completed in 1909, this dam stands at 45 feet in height and stretches 280 feet in length, holding a storage capacity of 42 acre-feet. Situated on the Spring Draw river, this structure is regulated by the Wyoming State Engineer's Office and undergoes regular inspections and enforcement to ensure its integrity.

Despite its low hazard potential, Pissolio No. 1 has been assessed as being in poor condition as of the last inspection in May 2017. With an emergency action plan yet to be prepared, there is a moderate risk associated with this dam, prompting the need for risk management measures to be implemented. The surrounding area is at risk of inundation in the event of a failure, highlighting the importance of maintaining and upgrading this vital water resource infrastructure.

As water resource and climate enthusiasts, it is crucial to monitor the condition of structures like Pissolio No. 1 to ensure the safety and sustainability of our water supply. With its rich history and essential role in irrigation, efforts must be made to address the poor condition of this dam and implement necessary risk management measures to mitigate any potential hazards. By staying informed and proactive, we can safeguard our water resources for future generations.
