Summary
Built in 1944, this earth dam stands at a height of 12 feet and a length of 350 feet, with a storage capacity of 150 acre-feet. Despite being privately owned, the dam is subject to state inspection and permitting, ensuring its structural integrity and compliance with regulations.
Situated on Salado Creek, the Ls Johnson Lake Dam plays a vital role in water resource management in the area, particularly during times of drought or increased water demand. With no spillway and a hazard potential that is not available, the dam's risk assessment is classified as high, highlighting the importance of regular inspections and maintenance to mitigate any potential risks. While the condition of the dam is not rated, its significance in supporting the local water supply underscores the need for continued monitoring and management.
As a part of the Fort Worth District, this dam is a key component in the water infrastructure of the region, contributing to the resilience of the community in the face of changing climate patterns and water availability. While specific details about its emergency action plan and risk management measures are not provided, the presence of outlet gates and state inspection requirements indicate a commitment to ensuring the safety and functionality of the Ls Johnson Lake Dam for the benefit of all who rely on its water supply services.

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.
