Summary
With a primary purpose listed as "Other," this earth dam with buttress core types reaches a structural height of 30 feet and boasts a storage capacity of 80 acre-feet. Despite its impressive stature, the dam has not been rated for its condition, signifying a potential hazard level of "High."
Surrounded by a surface area of 5 acres and serving a drainage area of 41 square miles, Helmich Lake Dam plays a vital role in water resource management in the region. With a maximum storage capacity of 80 acre-feet and a normal storage level of 50 acre-feet, the dam has a significant impact on the local water supply and flood control efforts. While lacking certain regulatory oversight and inspection frequency, the dam remains an essential component of the area's infrastructure.
As water resource and climate enthusiasts explore the intricate details of Helmich Lake Dam, its high hazard potential and unassessed condition raise questions about its long-term sustainability and safety measures. With emergency action plans yet to be fully developed and inspected, the dam's role in mitigating risks and managing water resources in the region presents a significant challenge. As stakeholders consider the implications of this critical infrastructure, ensuring the dam's resilience and effectiveness in the face of changing climate patterns becomes paramount.

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.
