Summary

Built with an earth dam type, the dam stands at a height of 12 feet and has a length of 415 feet, providing a storage capacity of 61 acre-feet for water from the Sheep Draw-TR river. The dam has a low hazard potential and is currently not rated for its condition, with the last inspection conducted in October 1987.

Despite its low hazard potential, Lundvall Dam #2 poses a high risk due to its outdated inspection date and lack of condition assessment. The dam does not have a spillway and does not meet current safety guidelines, raising concerns about its ability to withstand potential emergencies. Additionally, the dam's emergency action plan status, risk assessment, and risk management measures are all currently unknown, highlighting the need for updated safety protocols and oversight for this critical water resource structure.

As water resource and climate enthusiasts, it is crucial to monitor and advocate for the proper maintenance and modernization of dams like Lundvall Dam #2 to ensure the safety and sustainability of our water supply systems. With the dam's location in an area prone to droughts and extreme weather events, implementing necessary upgrades and safety measures will be essential in mitigating risks and protecting the surrounding communities and ecosystems from potential disasters.

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.
