Summary

This private earth dam stands at a height of 15 feet with a structural height of 13 feet, spanning a length of 767 feet along the TR-Cottonwood Creek. The dam has a maximum storage capacity of 96 acre-feet, with a normal storage level of 42 acre-feet.

Despite being unregulated by the state, Hasty Dam presents a high risk potential due to its condition not being rated. It lacks a spillway and has no associated inundation maps or emergency action plans prepared, raising concerns about its capacity to handle potential hazards effectively. The dam's hazard potential and risk assessment are both labeled as "Not Available", indicating a need for further inspection and management measures to ensure the safety of the surrounding area and water resources.

For water resource and climate enthusiasts, Hasty Dam stands as an intriguing case study of a privately owned structure with limited state oversight and a high risk potential. Its design and purpose for irrigation highlight the importance of proper maintenance and emergency preparedness in safeguarding against potential hazards and ensuring the sustainable use of water resources. As discussions on dam safety and climate resilience continue, Hasty Dam serves as a reminder of the need for proactive risk management and regulatory measures to protect our vital water infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
