Summary

Completed in 1986, this Earth dam stands at 26 feet tall and stretches 425 feet in length, with a storage capacity of 263 acre-feet. Despite its significant role in irrigation, Boerner faces challenges with a poor condition assessment and a low hazard potential, prompting the need for maintenance and risk management measures to ensure its continued functionality.

The dam's inspection frequency of every 5 years reveals a commitment to monitoring its structural integrity, but the last assessment in July 2018 highlighted the need for improvements. With a moderate risk assessment rating of 3, there is a recognition of potential vulnerabilities that may impact its effectiveness in the face of climate change and increasing water demands. Furthermore, the presence of an uncontrolled spillway and a single slide gate outlet raise concerns about the dam's ability to manage excess water and mitigate potential flooding events.

As climate enthusiasts and water resource advocates, it is crucial to monitor and support the maintenance efforts for dams like Boerner to ensure sustainable water management practices. By addressing the poor condition assessment, implementing risk management measures, and enhancing emergency preparedness, stakeholders can safeguard this vital irrigation infrastructure for the future. Collaborative efforts between private owners, regulatory agencies, and the community are essential to protect the integrity of dams like Boerner and sustainably manage water resources in the face of changing climate conditions.

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.
