Sediment Pond 16-1 is a privately owned earth dam located in Oliver County, North Dakota, along Square Butte Creek. Designed by Keith R. Yapp, PE, the dam stands at a height of 23 feet and stretches 800 feet in length, with a storage capacity of 267 acre-feet. The dam serves a primary purpose of sediment control and is regulated by the North Dakota State Water Commission, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.

With a spillway type of "Uncontrolled" and a spillway width of 75 feet, Sediment Pond 16-1 has a low hazard potential and a moderate risk assessment rating of 3. The dam features a vertical lift outlet gate and a stone core foundation, providing stability and reliability in managing water flow and storage. While the dam's condition is currently rated as "Not Rated," its moderate risk level indicates the need for ongoing monitoring and potential risk management measures to ensure its continued safety and effectiveness in sediment retention and water resource management.

Overall, Sediment Pond 16-1 plays a vital role in sediment control and water management in the region, with a focus on protecting water quality and downstream ecosystems. As a key infrastructure for environmental conservation and water resource sustainability, the dam's design, construction, and regulatory oversight underscore its importance in mitigating sediment runoff and preserving the health of Square Butte Creek and its surrounding watershed.
