Summary
Completed in 1963, this dam serves multiple purposes including fire protection, stock watering, and small fish pond habitat. With a height of 21 feet and a hydraulic height of 16 feet, Haines Stock has a storage capacity of 86 acre-feet and a surface area of 8 acres.
Despite being classified as having a low hazard potential, Haines Stock is regularly inspected by the state regulatory agency to ensure its structural integrity and overall condition. The dam is equipped with an uncontrolled spillway with a width of 200 feet, and there are no outlet gates associated with the structure. The last inspection in April 2017 deemed the dam to be in fair condition, with a moderate risk assessment rating of 3.
For water resource and climate enthusiasts, Haines Stock represents an important piece of infrastructure that plays a crucial role in providing water for livestock, fire protection, and supporting local wildlife. With its modest size and low hazard potential, this dam serves as a reminder of the intricate relationship between human development and natural resources in the region.

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.
