Summary

This earth-type dam stands at a height of 22 feet with a hydraulic height of 17 feet, serving the purpose of protecting the area from potential flooding along the Hemenway Wash-TR river or stream. With a storage capacity of 190 acre-feet, this dam plays a vital role in mitigating the risk of high hazard potential in the region.

Despite being uncontrolled, the dam features a spillway width of 600 feet to handle a maximum discharge of 15,000 cubic feet per second. The condition assessment of Bootleg Detention Basin Dam is rated as fair, with regular inspections to ensure its structural integrity and functionality. While the risk assessment is moderate, the emergency action plan and risk management measures for this dam are currently under review, highlighting the importance of maintaining and monitoring such critical infrastructure in the face of changing climate patterns and water resource management challenges.

In a region prone to flooding and with a high hazard potential, the Bootleg Detention Basin Dam stands as a significant line of defense against potential disasters. As climate change continues to impact water resources and weather patterns, the maintenance and management of such structures become increasingly crucial to safeguarding communities and infrastructure. With its strategic location and design, this dam serves as a vital asset in the local government's efforts to manage flood risk and protect the surrounding area from potential inundation.

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.
