Hardisty Wilson West, also known as Whitby Reservoir, is a privately owned water resource located in Owyhee, Idaho. This reservoir serves multiple purposes, including water storage for Juniper Creek and Wilson Creek. The dam, constructed in 1918, is primarily an earth and stone structure with a height of 18.4 meters and a storage capacity of 174 acre-feet.

Despite being classified as having a low hazard potential, Hardisty Wilson West underwent a fair condition assessment as of August 2017. The dam is regularly inspected and regulated by the Idaho Department of Water Resources, ensuring its structural integrity and safety. With a very high risk assessment ranking, measures for risk management and emergency preparedness may need to be further developed to address potential challenges.

Climate and water resource enthusiasts will find Hardisty Wilson West to be a fascinating example of early 20th-century dam construction and management practices. As part of the Sacramento District in Idaho, this reservoir plays a crucial role in the local water supply and ecosystem, highlighting the intersection of human infrastructure with natural resources in a dynamic and evolving environment.
