Located in Edwards, Kansas, the 1-2 Colglazier dam is a privately-owned Earth dam completed in 1999 with a height of 17.6 feet and a storage capacity of 211.6 acre-feet. The dam serves the primary purpose of controlling water flow on Sawmill Creek-TR and has a low hazard potential with a moderate risk assessment. The dam, designed by REH & Associates, is regulated by the Kansas Department of Agriculture and undergoes regular inspections and enforcement to ensure its safety and functionality in managing water resources in the region.

With a normal storage capacity of 20.6 acre-feet and a drainage area of 3.31 square miles, the 1-2 Colglazier dam plays a crucial role in managing water levels and mitigating flood risks in the area. The dam's spillway type is uncontrolled with a width of 70 feet, and it has no outlet gates or associated locks. Despite its low hazard potential, the dam is subject to moderate risk management measures to ensure its continued operation and safety for surrounding communities. The dam's location within the Kansas City District and under the jurisdiction of the state of Kansas underscores its importance in water resource management and climate resilience efforts.

As a key infrastructure for water resource management, the 1-2 Colglazier dam contributes to the overall resilience of the region against flooding and water scarcity challenges. With its construction completed over two decades ago, the dam continues to uphold its purpose of regulating water flow on Sawmill Creek-TR and protecting downstream areas. Regular inspections and enforcement by the Kansas Department of Agriculture ensure that the dam meets regulatory standards and poses no imminent threat to surrounding communities. The 1-2 Colglazier dam stands as a testament to the importance of sustainable water resource management in the face of changing climate dynamics and growing water resource demands.
