Clark No. 1, located in Niobrara, Wyoming, is a privately-owned earth dam constructed in 1959 for irrigation purposes along ALUM CREEK. Standing at 25 feet high with a spillway width of 250 feet, this structure has a storage capacity of 496 acre-feet and a surface area of 39 acres. Despite its low hazard potential, the dam's condition assessment in 2019 rated as poor, highlighting the need for maintenance and potential improvements to ensure its long-term stability.

Managed by the SEO agency in Wyoming, Clark No. 1 is subject to state regulation, permitting, inspection, and enforcement. The dam's last inspection in November 2019 revealed its poor condition, prompting a moderate risk assessment and raising concerns about its structural integrity. The presence of an uncontrolled spillway and a single valve for outlet gates further underscores the importance of regular monitoring and maintenance to mitigate potential risks associated with the dam.

With Liz Cheney (R) representing the Congressional District 00 in Wyoming, stakeholders involved in water resource management and climate adaptation should closely monitor the condition of Clark No. 1. As climate change continues to impact water availability and infrastructure resilience, ensuring the safety and functionality of dams like Clark No. 1 is crucial for sustainable water management and agricultural practices in the region. Collaborative efforts between private owners, regulatory agencies, and local communities will be essential in addressing the dam's poor condition and implementing risk management measures to protect surrounding areas from potential hazards.
