Summary
Managed by the Natural Resources Conservation Service, this earth dam stands at a height of 25 feet and was completed in 1956. With a storage capacity of 57 acre-feet and a normal storage of 34 acre-feet, Louder Number 1 serves the primary purpose of water resource management within the TR-WHITE RIVER watershed.
Despite its low hazard potential, Louder Number 1 has not been rated for its condition assessment. The dam's last inspection date, inspection frequency, and emergency preparedness details are not provided in the data. However, the dam has state permitting, inspection, and enforcement processes in place, ensuring regulatory compliance and safety standards. The surrounding area, including the nearby city of NONE, remains at a low risk level due to the dam's management and maintenance practices.
Overall, Louder Number 1 plays a crucial role in water management within the St. Paul District, offering essential storage and discharge capabilities for the TR-WHITE RIVER. While its specific risk assessment and emergency preparedness details are not outlined in the data, the dam continues to operate under state jurisdiction, with state-regulated processes in place to ensure its safety and functionality. Louder Number 1 stands as a vital infrastructure for water resource enthusiasts and climate advocates in the region.

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.
