Summary
The dam, with a height of 29 feet and a length of 590 feet, serves the primary purpose of flood risk reduction along Roy's Creek. With a storage capacity of 122 acre-feet and a normal storage level of 32.8 feet, the dam covers a surface area of 5.9 acres and has a drainage area of 0.31 square miles. Despite its low hazard potential, the dam's risk assessment is rated as moderate (3).
Although the dam is unlisted as a state-regulated structure and does not fall under state jurisdiction for permitting, inspection, or enforcement, its condition assessment is currently labeled as "Not Rated." The dam features an uncontrolled spillway with a width of 35 feet and does not have any outlet gates. While there have been no reported modifications to the dam since its completion, the emergency action plan (EAP) status, inundation maps, and risk management measures for Dd No 5-13a remain undisclosed. It is important for water resource and climate enthusiasts to stay informed about the condition and maintenance of dams like Dd No 5-13a to ensure their continued effectiveness in mitigating flood risks and protecting communities downstream.

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.
