The Upper Sand Creek Detention Basin in Contra Costa, California, is a crucial flood risk reduction infrastructure completed in 2014. This earth dam stands at a height of 40 feet and has a maximum storage capacity of 895 acre-feet, serving its primary purpose effectively. The basin covers a surface area of 44 acres and plays a vital role in managing the flow of the Sand Creek river, safeguarding the surrounding areas from potential flooding events.

Managed by the local government and regulated by the Department of Water Resources (DWR), Safety of Dams division, the Upper Sand Creek Detention Basin is inspected regularly to ensure its structural integrity and safety. With a high hazard potential but a satisfactory condition assessment as of September 2017, the basin remains a critical asset in the region's water resource management strategy. Despite lacking detailed risk management measures and emergency preparedness plans, the basin's presence aligns with the state's commitment to mitigating flood risks and protecting communities in California.

Supported by federal and state regulations, the Upper Sand Creek Detention Basin stands as a testament to proactive flood risk reduction efforts in the region. With a dedicated focus on safety and efficiency, this infrastructure project highlights the importance of sustainable water resource management in the face of changing climate patterns. As water resource and climate enthusiasts, the basin serves as a symbol of resilience and preparedness in safeguarding communities against the impacts of extreme weather events.
