Summary

Paul District. Completed in 1940, this dam serves multiple purposes, including fire protection, stock, and small fish pond management. With a height of 14 feet and a storage capacity of 110 acre-feet, Boocke No 2 (Nid) plays a crucial role in maintaining the water resources in the region.

Despite being categorized as low hazard potential and not currently rated for condition assessment, Boocke No 2 (Nid) presents a moderate risk level. The dam has a normal storage capacity of 110 acre-feet and can discharge up to 620 cubic feet per second through an uncontrolled spillway. Although last inspected in 2006 and with an inspection frequency of 10 years, there is a need for regular monitoring and maintenance to ensure its continued safety and functionality, especially with changing climate conditions impacting water resources.

As climate change continues to affect water resources, dams like Boocke No 2 (Nid) play a critical role in water management and protection. With its primary purpose of fire protection and water storage, this dam serves as a vital asset in the region's ecosystem and wildlife conservation efforts. As enthusiasts in water resource and climate advocacy, understanding and monitoring the condition of infrastructure like Boocke No 2 (Nid) is essential for sustainable water management and resilience in the face of climate challenges.

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.
