Summary
6. Completed in 1972 by Dale L. Hoffmann, the dam stands at a height of 49 feet and serves purposes such as fire protection, stock, and small fish pond. It has a storage capacity of 82 acre-feet and covers a surface area of 5.21 acres, with a drainage area of 0.32 square miles. The dam's spillway type is uncontrolled, with a width of 29 feet, and it is equipped with one valve outlet gate.
Despite being classified as having a low hazard potential, Bow & Arrow 4-25 received a fair condition assessment during its last inspection in August 2018. The dam's risk assessment is moderate, with a DSAC (Dam Safety Action Classification) assigned as 3. The inspection frequency is set at 5 years, and the dam is regulated by the State Engineer's Office in Wyoming. The surrounding area is at moderate risk, and there are no specific risk management measures or guidelines in place at this time. Overall, Bow & Arrow 4-25 is a critical water resource structure for fire protection and livestock management in the region, with a cautious eye on its safety and maintenance.

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.
