Summary
This privately owned Earth dam stands at a height of 14 feet and has a length of 1110 feet, with a storage capacity of 70 acre-feet. Situated on the Nueces River, the dam plays a crucial role in regulating water flow and providing essential irrigation and recreational opportunities for the surrounding area.
Despite its age, Nueces Ranch Lake Dam has not been rated for its condition assessment, and its hazard potential is listed as "Not Available." With a risk assessment of "High (2)," there may be concerns about its structural integrity and safety in the event of an emergency. While the dam does not have a spillway, it is equipped with one outlet gate for water release. The Fort Worth District of the US Army Corps of Engineers does not oversee this dam, and it is not subject to federal regulation.
Water resource and climate enthusiasts will find Nueces Ranch Lake Dam to be a fascinating case study in private dam ownership and management. This dam's role in water storage, irrigation, and flood control on the Nueces River highlights the importance of sustainable water resource practices in the face of changing climate patterns. As discussions around water security and infrastructure resilience continue to evolve, the future of Nueces Ranch Lake Dam will be closely monitored to ensure its continued effectiveness and safety for the surrounding community.

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.
