Summary
Completed in 1951, this dam stands at a height of 37 feet and has a hydraulic height of 31 feet, providing a maximum storage capacity of 100 acre-feet. The dam, constructed of stone core and soil foundation, spans a length of 210 feet and features a controlled spillway with a width of 1 foot.
Despite being rated as having low hazard potential, the risk assessment for SCS-Sandstone Creek Site-101 indicates a very high risk level, with a DSAC assigned date unknown. The dam is equipped with one valve outlet gate and has not been inspected since January 1, 1980. While the condition assessment is listed as "Not Rated," it is important to note that emergency action plans, inundation maps, and risk management measures have not been updated or prepared for this site. Overall, this dam serves a critical function in mitigating flood risks along the TR-East Fork Sandstone Creek, but there is a need for further evaluation and maintenance to ensure its long-term safety and effectiveness in 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.
