Summary
6, also known as Garfield Dam, was completed in 1957 by the USDA NRCS. With a primary purpose of flood risk reduction, this earth dam stands at 53 feet high and stretches 900 feet in length along the Garfield Arroyo. The dam has a storage capacity of 326 acre-feet and a maximum discharge of 10,900 cubic feet per second, making it a crucial infrastructure for managing water resources in the area.
Despite its importance, the Hatch Valley Arroyo Dam No. 6 has been rated as having a high hazard potential and poor condition assessment. The dam's last inspection in February 2020 revealed concerning issues, prompting a moderate risk assessment. With the Office of the State Engineer overseeing its regulation and enforcement, the dam requires regular inspection and maintenance to ensure its structural integrity and continued effectiveness in flood risk reduction. Climate and water resource enthusiasts should keep an eye on developments surrounding this critical piece of infrastructure in New Mexico.

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.
