Summary
This privately owned irrigation system draws water from Pole Creek to provide water for irrigation purposes. The dam associated with the system is an earth-filled structure with a height of 47 feet and a length of 1160 feet, completed in 1972. With a storage capacity of 846 acre-feet, the system plays a crucial role in managing water resources for the local community.
Despite its importance, Pole Creek Irrigation faces significant challenges in terms of its condition assessment, which has been rated as poor. The inspection frequency is set at every 5 years, with the last inspection conducted in August 2018. The hazard potential is deemed significant, pointing to the need for immediate attention and maintenance. The system's emergency action plan (EAP) status and risk management measures are currently not specified, indicating potential areas for improvement in emergency preparedness and response.
Given its moderate risk level and the importance of the irrigation system for local agriculture, stakeholders and regulatory agencies should prioritize addressing the identified maintenance issues and enhancing emergency preparedness measures for Pole Creek Irrigation. With its critical role in water resource management, safeguarding the integrity and functionality of the infrastructure is essential for ensuring sustainable water use and agricultural productivity in the region.

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.
