Summary
This Earth-type dam stands at 17 feet in height and spans 1340 feet in length, completed in 1958. It has a storage capacity of 102 acre-feet and a maximum discharge rate of 858 cubic feet per second, with a controlled spillway width of 1 foot.
Despite its low hazard potential, the dam's risk assessment is categorized as very high, emphasizing the importance of regular inspections and maintenance. The last recorded inspection date was in 1980, with an inspection frequency of every 5 years. The dam is equipped with a single valve outlet gate and is not currently rated for its condition assessment.
Water resource and climate enthusiasts would find SCS-Mill Creek Site-09 an intriguing structure due to its historical significance in flood risk management and the potential challenges it faces in terms of risk management and maintenance. The dam's location in the Fort Worth District, with the TR-Mill Creek river/stream running through it, offers a unique opportunity for studying the impact of climate change on water infrastructure in the region. Further research and monitoring of this site could provide valuable insights into sustainable water resource management practices in the face of changing environmental conditions.

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.
