Summary

This privately owned Earth dam stands at a height of 24 feet and has a storage capacity of 150 acre-feet. The dam's primary purpose and associated structures are not specified, but it serves as a crucial water resource in the region.

Despite being classified as a low hazard potential structure with a moderate risk assessment, Lindskov Dam has not been inspected since September 1999. The dam features an uncontrolled spillway with a width of 50 feet, capable of handling a maximum discharge of 675 cubic feet per second. The condition assessment is currently listed as "Not Rated," highlighting the need for updated inspection and maintenance protocols to ensure the safety and efficiency of this vital water management infrastructure.

As water resource and climate enthusiasts continue to monitor the implications of aging infrastructure on water security and environmental resilience, Lindskov Dam serves as a poignant reminder of the importance of regular maintenance and inspection to mitigate potential risks. With the dam falling under state regulation and inspection, stakeholders are urged to prioritize the assessment and upkeep of this essential structure to safeguard both the local community and the surrounding ecosystem from the impacts of any unforeseen incidents.

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.
