Summary
This dam plays a critical role in water resource management as it regulates the flow of the tributary North Fork Moreau, with a storage capacity of 54 acre-feet. Despite being classified as having low hazard potential, the dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources to ensure its safety and compliance with state regulations.
With a normal storage capacity of 30 acre-feet and a maximum discharge of 525 cubic feet per second, Lale Pond No.2 serves as an important structure for managing water resources in the region. Although the dam's condition is currently listed as "Not Rated," regular inspections are conducted to monitor its integrity and address any potential risks. The dam is also equipped with outlet gates, but details on other associated structures and maintenance activities are not specified in the available data.
Overall, Lale Pond No.2 stands as a vital component of the water infrastructure in South Dakota, contributing to both water resource management and climate resilience efforts in the area. Its presence provides essential regulation of water flow and storage capacity, highlighting the importance of proper maintenance and oversight to ensure its continued functionality and safety for the surrounding communities and ecosystems.

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.
