Summary

Owned privately, this earth dam structure stands at a height of 13 feet and has a storage capacity of 385 acre-feet. Situated along Lambs Creek, the pond covers a surface area of 22 acres, with a drainage area of 0.6 square miles.

Despite its importance, Sedimentation Pond No 10 has not been rated for its condition, posing a potential risk due to its high hazard level. The dam lacks a spillway and outlet gates, raising concerns about its ability to manage water discharge effectively. The last inspection of the structure was conducted in February 2011, and there is limited information available on its maintenance and emergency preparedness protocols.

As water resource and climate enthusiasts, the data surrounding Sedimentation Pond No 10 highlights the need for continued monitoring and assessment of critical infrastructure to ensure the safety and sustainability of water resources in the region. With the potential for high-risk situations and limited regulatory oversight, there is a call to action for increased scrutiny and investment in the maintenance and management of such vital structures to mitigate potential environmental hazards and ensure the long-term health of water ecosystems.

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.
