Summary
This private earth dam stands at a height of 10 feet and stretches over 930 feet, with a storage capacity of 66 acre-feet. Situated on the TR-Nueces River, this dam plays a crucial role in managing water resources in the area.
Despite being state-permitted and inspected, Guajardo Ranch Dam No1 68 has not been rated for its condition and is considered to have a high hazard potential. With no spillway and limited information on its risk management measures, this dam poses a potential risk to surrounding communities in the event of a failure. The dam is not owned or funded by any federal agency, highlighting the importance of private owners maintaining the safety and integrity of this structure.
As water resource and climate enthusiasts, it is important to recognize the vital role that dams like Guajardo Ranch Dam No1 68 play in water management and conservation efforts. With its high hazard potential and lack of detailed risk assessment, it is crucial for private owners and regulatory agencies to prioritize regular inspections and maintenance to ensure the safety of the surrounding area and the longevity of this important water resource infrastructure.

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.
