Summary
Completed in 1938 by the Forest Service, this earth dam stands at a height of 17 feet and has a storage capacity of 80 acre-feet. Its primary purposes include fire protection, stock watering, and serving as a small fish pond, with additional functions for fish and wildlife management. The dam is situated on the Dry Draw river, within the St. Paul District of the US Army Corps of Engineers.
Despite being classified as having a low hazard potential, Bower (Nid) is subject to a moderate risk assessment, emphasizing the importance of proactive risk management measures. The dam has not been rated for its condition, with the last inspection dating back to October 2006. While the structure itself has not undergone significant modifications over the years, its spillway remains uncontrolled. The surrounding area is not densely populated, which contributes to the lower risk profile associated with the dam.
With a relatively small drainage area of 1 square mile and a maximum discharge capacity of 744 cubic feet per second, Bower (Nid) serves as a crucial water source for the local ecosystem. As climate change continues to impact water resources worldwide, monitoring and maintaining structures like Bower (Nid) are essential for ensuring water security and ecosystem health in the region.

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.
