Summary
The dam, primarily owned by a private entity, is an earth dam type with a height of 20 feet and a length of 600 feet. It stores 176 acre-feet of water and covers a surface area of 12 acres.
Although the dam does not have a spillway, it is equipped with one outlet gate. Despite being privately owned, the dam is regulated by the state with permitting and inspection requirements in place. The condition assessment of the dam is currently listed as "not rated" and it has a high risk assessment rating, indicating potential hazards that need to be addressed.
Water resource and climate enthusiasts may be interested in monitoring the maintenance and risk management measures of Ellwood Lake Dam, as it plays a crucial role in providing water for fire protection and livestock in the region. The dam's location on Hackberry Creek within the Fort Worth District presents unique challenges and opportunities for sustainable water management practices. Further research and monitoring of the dam's condition and regulatory compliance could provide valuable insights into the intersection of water resource management and climate resilience in Texas.

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.
