Shutter is a privately owned irrigation dam located in Wyoming, specifically in Campbell County near the city of Wormwood Ranch. Completed in 2009, this earth dam stands at 32 feet in height and spans 440 feet in length, with a maximum storage capacity of 106 acre-feet. Its primary purpose is irrigation, serving the needs of the surrounding area for fire protection, stock watering, and small fish pond support.

The dam's design includes a stone core and soil foundation, with a spillway width of 60 feet to manage a maximum discharge of 2180 cubic feet per second. Despite its low hazard potential and fair condition assessment, the dam is subject to regular inspections every five years to ensure its safety and structural integrity. While it has not been modified in recent years, Shutter remains a crucial water resource for the local community, contributing to the overall water management efforts in the region.

Managed by the Wyoming State Engineer's Office and falling under state jurisdiction, Shutter plays a vital role in water conservation and distribution within the Skinny Fork Draw watershed. With its moderate risk assessment rating and compliance with state permitting and inspection requirements, this dam represents a key piece of infrastructure supporting sustainable water use and environmental stewardship in the area.
