Summary

This earth dam stands at a height of 25 feet with a structural height of 26 feet and a length of 320 feet, offering a storage capacity of 46 acre-feet for flood control and water resource management in the area. With a low hazard potential and moderate risk assessment, this dam plays a crucial role in mitigating potential risks and ensuring the safety of the surrounding community.

Managed by a private owner, Buck & Doe Run Watershed Dam Lt-58 is not state-regulated or permitted, reflecting its unique status within the region. Despite being unregulated, the dam's design and construction follow industry standards, with a stone core and soil foundation providing stability and resilience. The dam's spillway type is uncontrolled, with a spillway width of 12 feet to manage excess water flow. With a surface area of 2.7 acres and a drainage area of 128 square miles, this dam serves as a vital infrastructure for maintaining water quality and protecting the ecosystem of the surrounding area.

As a significant landmark in the Rock Island District, Buck & Doe Run Watershed Dam Lt-58 is an essential component of the local water resource infrastructure. While its condition assessment is not rated, the dam continues to fulfill its role in grade stabilization and flood control, contributing to the overall resilience of the region. With a focus on risk management and emergency preparedness, this dam exemplifies the importance of sustainable water resource management in the face of changing climate patterns and environmental 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.
