Summary

This private-owned earth dam stands at a height of 15 feet and spans 790 feet in length, with a storage capacity of 200 acre-feet. Situated on the TR-Sabana River, the dam plays a crucial role in providing water resources for agricultural activities in the region.

Despite its age, Mcginnis Dam has not been rated for its condition assessment, and its hazard potential is not available. However, the risk assessment for the dam is considered high (2), highlighting the importance of regular inspections and maintenance to ensure its safety and reliability. With no spillway and limited information on its infrastructure, there is a need for further evaluation to mitigate any potential risks associated with the dam.

As water resource and climate enthusiasts, it is essential to monitor the condition of structures like Mcginnis Dam to safeguard water security and prevent potential disasters. With its historical significance in irrigation and water management, the dam serves as a reminder of the critical role of infrastructure in sustaining agricultural activities and supporting local communities. As efforts continue to maintain and improve the dam's safety, it remains a key asset in the region's water resource management system.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
