Summary
This privately-owned earth dam stands at a height of 25 feet and spans a length of 620 feet, with a storage capacity of 190 acre-feet. Despite being non-regulated by the state, the dam has been designed with a buttress core and has a high hazard potential rating.
The dam lacks a spillway and is equipped with only one outlet gate. With a risk assessment rating of high (2), the condition of Drechsel Lake Dam is currently not rated. While the dam has not been modified in recent years and does not have an emergency action plan in place, it is monitored for inspection and permitting by the state of Texas. With its strategic location and critical role in water supply, Drechsel Lake Dam serves as a notable feature within the Fort Worth District, attracting water resource and climate enthusiasts interested in infrastructure and environmental management.
Overall, Drechsel Lake Dam presents an intriguing case study for water resource and climate enthusiasts, showcasing the intersection of private ownership, infrastructure design, and regulatory oversight in the context of water supply management. Its location along Mustang Creek in Texas, with a high hazard potential and lack of spillway, raises questions about risk management and emergency preparedness. As stakeholders continue to monitor and assess the condition of Drechsel Lake Dam, it serves as a reminder of the importance of sustainable water resource practices in the face of changing climate patterns and increasing demands for water supply.

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.
