Summary
Constructed in 1951 and standing at a height of 32 feet, this dam on the TR-East Fork of Sandstone Creek plays a crucial role in safeguarding the surrounding area from potential flooding events. With a maximum storage capacity of 250 acre-feet and a controlled spillway type, this structure is well-equipped to handle up to 1000 cubic feet per second of discharge.
Despite being rated as having a low hazard potential and not yet assessed for its condition, the SCS-Sandstone Creek Site-103a poses a very high risk due to its location and the potential consequences of failure. The dam is equipped with a single valve outlet gate and undergoes inspections every 5 years for maintenance and monitoring purposes. While the emergency action plan (EAP) status and risk management measures are not specified, the dam's risk assessment indicates the need for proactive measures and preparedness in case of emergencies. Overall, this site serves as a critical infrastructure for flood control in the region, highlighting the importance of water resource management and climate resilience efforts.

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.
