Summary
This privately owned dam, with a height of 45 feet and length of 400 feet, was completed for the primary purpose of providing water resources for various activities in the area. Situated on Conner Creek, the dam has a storage capacity of 150 acre-feet and has been inspected in the past for safety and regulatory compliance.
Despite being classified as "Not Rated" in terms of condition assessment, the dam presents a high risk potential (2) according to the available data. With no spillway and limited information on its structural design, the dam's hazard potential and risk management measures remain unspecified. The last inspection date recorded for Mcgarrahan Dam was in October 1989, raising concerns about the need for updated assessments and emergency action plans to ensure the safety and effectiveness of this essential water resource infrastructure for the community.
For water resource and climate enthusiasts, Mcgarrahan Dam represents a significant structure contributing to the local ecosystem by providing water for fire protection, agriculture, and wildlife. The dam's location, dimensions, and purpose underscore the importance of sustainable management and risk assessment in safeguarding water resources and enhancing resilience to potential climate-related challenges. As the dam continues to support various activities in the region, ongoing monitoring and maintenance efforts are crucial to ensure its long-term functionality and safety for the surrounding communities and environment.

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.
