Widener is a privately owned irrigation dam located in Sheridan, Wyoming, on the Apple Run river. Built in 1997, this earth dam stands at 25 feet high and spans 472 feet in length, providing vital water storage for irrigation purposes. Despite its low hazard potential, the dam is currently in poor condition according to a 2017 assessment, posing a moderate risk that requires attention.

Even though Widener serves primarily for irrigation, it also supports fire protection, stock watering, and fish and wildlife habitats. With a normal storage capacity of 28 acre-feet and a maximum storage of 50 acre-feet, this dam covers a surface area of 4.2 acres and drains an area of 1.07 square miles. With one valve outlet gate and an uncontrolled spillway, Widener has been inspected periodically, with the last inspection taking place in September 2017.

In the scenic landscape of UNNAMED RANCH, Widener plays a crucial role in managing water resources for agricultural activities in the region. As climate change continues to impact water availability, the maintenance and monitoring of dams like Widener are essential to ensure sustainable water management practices and safeguard against potential risks associated with aging infrastructure.
