Summary
The dam stands at a height of 22 feet with a structural height of 17 feet and a length of 12,025 feet. It has a storage capacity of 4,460 acre-feet and covers a surface area of 75 acres, serving as a crucial water resource in the region.
Despite its low hazard potential, the dam's condition assessment is currently not rated, and there is no information available on its emergency action plan or risk management measures. The surrounding area's drainage area is listed as zero, with the dam impounding an unnamed pond. While the dam plays a vital role in water resource management, further inspection and assessment may be necessary to ensure its continued safety and functionality in the face of changing climate conditions.
With its location in a region vulnerable to climate impacts and increasing water resource demands, stakeholders and climate enthusiasts should monitor developments regarding the condition and regulatory oversight of Silver City Sa No 7. Understanding the dam's capacity, maintenance needs, and emergency preparedness is crucial for safeguarding the local community and water resources in the face of potential climate-related challenges. Continued attention to this dam and others like it is essential for sustainable water resource management in the region.

Dam Data Reference
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.
