Summary
Built in 1948, this earth dam stands at a height of 40 feet and has a normal storage capacity of 508 acre-feet. Managed by the local government, the dam is regulated by the Wyoming State Engineer's Office and undergoes regular inspections to ensure its structural integrity and compliance with safety standards.
With a significant hazard potential and a fair condition assessment as of the last inspection in 2019, Cody Municipal plays a crucial role in water resource management for the region. The dam, designed by Alfred J. Ryan, features a slide (sluice gate) outlet gate and serves as the primary source of water supply for the area. Despite its age, the dam continues to meet the water needs of the community, highlighting the importance of robust infrastructure in sustaining water resources amidst changing climates and increasing demands.
As climate change poses challenges to water availability and quality, the maintenance and monitoring of structures like Cody Municipal become increasingly vital. With a high risk assessment rating, the dam underscores the need for proactive risk management measures to ensure the safety and reliability of water resources in the face of evolving environmental pressures. As water enthusiasts and climate advocates, understanding the critical role of infrastructure like Cody Municipal is essential in safeguarding water sources for future generations.

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.
