Located in Delta, Colorado, Porter #1, also known as Big Davies, is a crucial water resource structure owned by the local government. This earth dam, completed in 1955, serves primarily for water supply purposes including irrigation. With a dam height of 31 feet and a storage capacity of 276 acre-feet, Porter #1 plays a significant role in managing water resources in the region.

Despite being categorized as low hazard potential with fair condition assessment, Porter #1 poses high risks, prompting the need for regular inspections and risk management measures. The dam, situated on Oak Creek, has a spillway width of 30 feet and a maximum discharge capacity of 849 cubic feet per second. The structure, constructed with stone core and rock-soil foundations, has a structural height of 33 feet and a length of 520 feet, providing essential water storage and management capabilities for the area.

In the event of emergencies, the structure lacks an Emergency Action Plan (EAP) and updated contact information, underscoring the importance of preparedness and risk assessment. As a vital water supply asset in Colorado, Porter #1 warrants continued monitoring and maintenance to ensure its reliability and safety for both water resource management and climate resilience in the region.
