Summary
Built in 1912, this earth dam stands at a height of 20 feet and has a storage capacity of 564 acre-feet. Primarily used for irrigation purposes, Haines is regulated and inspected by the Wyoming State Engineer's Office, ensuring its safety and compliance with state regulations.
Despite its low hazard potential, Haines is currently assessed to be in poor condition, with a moderate risk rating of 3. Its spillway is uncontrolled, with a width of 6 feet, and the dam has not been modified in recent years. The last inspection was conducted in May 2020, with a scheduled inspection frequency of every 5 years. While the dam is considered to be in poor condition, it continues to serve its purpose of providing water for irrigation in the region.
For water resource and climate enthusiasts, Haines presents an interesting case study of an aging irrigation dam in Wyoming. The dam's location on North Spring Creek offstream and its stone core and soil foundation add to its unique characteristics. With its historical significance dating back over a century, Haines serves as a reminder of the importance of maintaining and monitoring the condition of infrastructure to ensure the safety and efficiency of water resources in the face of changing climate conditions.

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.
