Summary
This earth dam structure primarily serves irrigation purposes, with a storage capacity of 224.8 acre-feet and a surface area of 89.9 acres. The dam stands at a height of 27.5 feet and has an uncontrolled spillway with a width of 40 feet, making it a crucial resource for water management in the region.
Despite being categorized as having a low hazard potential, Haumont Tank is subject to regular inspections to ensure its structural integrity and safety standards. The last recorded inspection was conducted in November 2009, with a scheduled inspection frequency of 5 years. While the condition assessment is currently listed as not rated, the risk assessment for the dam is considered moderate, indicating a need for ongoing monitoring and risk management measures to safeguard against potential hazards.
With its strategic location and essential role in irrigation and water resource management, Haumont Tank represents a significant infrastructure asset in the region. As climate change continues to impact water availability and usage patterns, the proper maintenance and regulation of structures like Haumont Tank are crucial for ensuring sustainable water access and addressing the evolving challenges posed by a changing climate.

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.
