Mcgarraugh Dam No 1 Reservoir Report
Nearby: John Hankins Dam Detrixhe
Last Updated: December 7, 2025
Mcgarraugh Dam No 1, located in Canadian, Texas, along the TR-CANADIAN RIVER, was completed in 1984 by the USDA NRCS with a primary purpose of flood risk reduction.

Summary
This private dam stands at 25 feet tall and stretches 515 feet in length, providing a storage capacity of 112 acre-feet for the surrounding drainage area of 1500 acres. Despite its age, the dam's condition assessment is currently rated as "Not Rated," with a high hazard potential ranking of 2.
Owned and operated by a private entity, Mcgarraugh Dam No 1 is not under state jurisdiction but is subject to state permitting, inspection, and enforcement. The dam's design features an earth core type with a buttress foundation, while lacking a spillway for controlled water release. With no associated structures and limited emergency preparedness measures in place, the dam is deemed to have a high risk factor, necessitating ongoing risk management strategies to ensure the safety of downstream communities and infrastructure. Though the dam is not regulated by federal agencies, it stands as a critical component in the local flood risk reduction efforts along the TR-CANADIAN RIVER.

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.
