Summary
Dixon, located in Johnson, Wyoming, is a Federal-owned Earth dam completed in 1956 for the primary purpose of serving as a Fish and Wildlife Pond. This structure on Dixon Draw has a dam height of 35 feet and a hydraulic height of 32 feet, with a storage capacity of 314 acre-feet and a normal storage of 163 acre-feet. The dam stretches 600 feet in length and covers a surface area of 16.6 acres, with a drainage area of 4.6 square miles.
Managed by the Omaha District of the US Army Corps of Engineers, Enl. Dixon has a low hazard potential and was last assessed to be in fair condition in May 2018. The dam's spillway is uncontrolled and has a width of 20 feet, with a maximum discharge capability of 4787 cubic feet per second. Despite its moderate risk assessment rating, Enl. Dixon remains vital for fire protection, stock watering, and promoting fish and wildlife habitats in the area.
Enthusiasts interested in water resources and climate dynamics will find Enl. Dixon to be a significant structure in the region, contributing to both ecological preservation and community safety. With its strategic location and multi-functional design, this dam serves as a key asset for maintaining water resources and supporting biodiversity in the Johnson, Wyoming area.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
