Summary
Owned privately, the dam is an earth-type structure with a buttress core, reaching a height of 25 feet and offering a storage capacity of 107 acre-feet. Located on the TR-Goodwater Creek in Mexico, the dam contributes significantly to the drainage area of 162 square miles, providing essential water resources for the surrounding agricultural lands.
Despite its importance for irrigation, Sudbrock Lake Dam poses a high hazard potential due to its structural condition being currently unrated. The dam's emergency action plan status, risk assessments, and inundation maps remain unprepared, raising concerns about its safety and management during potential emergencies. With no federal or state regulatory oversight, the dam's operation and maintenance are solely in the hands of its private owner, emphasizing the need for proactive risk management measures to ensure the safety of the surrounding communities and water resources in the area.
As water resource and climate enthusiasts delve into the details of Sudbrock Lake Dam, the absence of formal inspections, condition assessments, and hazard mitigation strategies highlight the challenges faced by privately-owned dams in ensuring their safety and reliability. The dam's significance in supporting irrigation activities underscores the importance of implementing robust management practices, emergency response plans, and risk assessment measures to safeguard both the dam's integrity and the local environment. With its high hazard potential and critical role in water supply management, Sudbrock Lake Dam serves as a reminder of the need for proactive monitoring and maintenance of essential water infrastructure for sustainable resource management.

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.
