Duggan is a privately owned earth dam situated in Gold Hill, Oregon, along the Snider Creek. Built in 1965 for recreational purposes, the dam stands at a height of 23 feet and has a storage capacity of 50 acre-feet. Despite its primary purpose of recreation, Duggan poses a high hazard potential with a poor condition assessment as of July 2021.

The dam's inspection frequency is once a year, with the last inspection conducted in July 2021. It is regulated by the Oregon Water Resources Department and meets state permitting, inspection, and enforcement requirements. The dam has a needle outlet gate and a spillway type is not specified. With a drainage area of 0.33 square miles and a maximum discharge of 200 cubic feet per second, Duggan plays a crucial role in managing water resources in the area.

Given its high hazard potential and poor condition assessment, it is essential for water resource and climate enthusiasts to monitor Duggan closely. The dam's location, along with its structural specifications and regulatory oversight, make it a key component in the water management infrastructure of Jackson County, Oregon. Continued monitoring, risk assessment, and management measures are crucial to ensure the safety and sustainability of Duggan for both recreational and water resource purposes.
