Summary
Built in 1960 with a primary purpose of debris control, this gravity dam stands at a structural height of 32 feet and has a hydraulic height of 27 feet. Situated on the Hurricane Wash tributary, this dam plays a crucial role in mitigating the risk of debris flow and enhancing water resource management in the region.
With a storage capacity of 1150 acre-feet and a surface area of 178 acres, Hole-N-Wall Detention Dam serves as a vital infrastructure for flood control and water conservation. The dam's uncontrolled spillway, with a width of 3 feet, can handle a maximum discharge of 840 cubic feet per second. Despite being classified as having a low hazard potential and fair condition assessment, regular inspections are conducted every 5 years to ensure the dam's structural integrity and operational effectiveness.
Managed by the Bureau of Land Management, Hole-N-Wall Detention Dam is an essential component of the region's water resource infrastructure. With a moderate risk rating and a history of maintenance and oversight, this gravity dam continues to play a pivotal role in protecting downstream communities and enhancing the overall resilience of the local water system.

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.
