Summary
Standing at a height of 15.2 meters and with a length of 486 meters, this dam has a storage capacity of 946 acre-feet and covers a surface area of 186.7 acres. Despite its low hazard potential, Long Point Dam is regulated and inspected by the Arizona Department of Water Resources, ensuring its structural integrity and safety.
The dam's spillway, classified as uncontrolled, has a width of 20 meters, contributing to its moderate risk assessment level. While the dam has not been rated for condition assessment, it undergoes regular inspections every five years to maintain its safety standards. Long Point Dam's location on Farm Dam Draw, within the jurisdiction of Arizona, highlights its significance in water resource management and climate resilience efforts in the region.
With its strategic positioning and role in water management, Long Point Dam plays a crucial part in supporting local ecosystems, providing water for agricultural needs, and safeguarding against potential flooding events. As a key infrastructure for the community, the dam's maintenance and regulation ensure its continued contribution to water resource sustainability and climate adaptation in Coconino, Arizona.

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.
