Summary
Constructed in 2007 by VELVIN & WEEKS, this Earth-type dam stands at a height of 40.8 feet with a hydraulic height of 37 feet and a structural height of 63.1 feet. With a storage capacity of 3,877 acre-feet and a surface area of 140 acres, Leonard Lake serves various purposes, including flood control and water supply for the surrounding area with a drainage area of 6.9 square miles.
The dam features an uncontrolled spillway with a width of 200 feet and outlet gates for operational control. The maximum discharge capacity of the dam is 8,412 cubic feet per second, providing essential safety measures for potential emergencies. Despite being rated as "Not Available" in terms of hazard potential and "Not Rated" in condition assessment, Leonard Lake is considered to have a moderate risk level based on risk assessment. The dam has not been inspected since September 2007, indicating a need for regular monitoring and maintenance to ensure its integrity and safety for the community.
With its strategic location on Indian Creek and proximity to Fort Worth District, Leonard Lake plays a crucial role in water resource management in the region. As a key infrastructure project, it highlights the collaboration between private stakeholders and state regulatory agencies in ensuring water security and environmental protection. Continuous monitoring and risk management measures are essential to safeguard the dam's structural integrity and functionality for the benefit of the local community and the surrounding ecosystem.

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.
