Summary

With a height of 13 feet and a length of 1100 feet, the dam has a storage capacity of 66.5 acre-feet and covers a surface area of 6.7 acres. The dam is situated on the Kill Creek-TR river or stream and falls under the jurisdiction of the state regulatory agency.

While Dam A has a low hazard potential and has not been rated for its condition assessment, it is equipped with a spillway width of 24 feet and has no associated locks. The last inspection of the dam was conducted in March 2007, and emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps have not been reported. Despite these limitations, Dam A remains a vital resource for local irrigation and recreational activities in the area.

For water resource and climate enthusiasts, Dam A serves as a noteworthy example of a privately-owned structure contributing to water management in the region. As interest in sustainable water practices continues to grow, monitoring and assessing the condition of dams like Dam A will be crucial to ensuring their long-term effectiveness and safety for both the environment and surrounding communities.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
