Summary
This private earth dam stands at a height of 14 feet and spans 975 feet in length. It impounds Pendleton Creek, creating a surface area of 180 acres and a maximum storage capacity of 1,649 acre-feet. Despite being uncontrolled, the dam has a low hazard potential and is classified as having a moderate risk level.
The dam, owned privately, is not regulated by the state but undergoes inspections every five years. Its primary purpose of recreation aligns with its surroundings at Shiloh Cemetery Environment, offering opportunities for leisure and enjoyment for locals and visitors alike. The dam's condition is currently not rated, and it carries out uncontrolled spillway operations with an outlet gate system in place. The risk assessment deems the dam to have a moderate risk level, highlighting the importance of ongoing monitoring and maintenance to ensure its structural integrity and safety for the surrounding community.
Sand Hill Lake Dam is an integral part of the local landscape, providing both recreational opportunities and a water resource for the area. With its historical significance dating back to the 1960s, the dam serves as a reminder of the importance of proper infrastructure management and risk assessment in the face of changing climate patterns. Enthusiasts of water resources and climate will find the details of this dam's design, construction, and current condition to be a fascinating case study in the intersection of human development and environmental stewardship.

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.
