Summary
Completed in 1990, this earth dam stands at a height of 24 feet, with a hydraulic height of 25 feet and a structural height of 28 feet. The dam stretches 600 feet in length and has a storage capacity of 122 acre-feet, making it a vital resource for managing water in the area.
Despite its importance for irrigation, the dam's condition assessment is rated as poor, with a hazard potential of low. The last inspection in April 2020 revealed the need for improvements to ensure its long-term viability. With a drainage area of 0.5 square miles and a normal storage capacity of 57 acre-feet, the dam plays a critical role in supporting agricultural activities in the region. However, its current state underscores the importance of ongoing maintenance and inspection to mitigate any potential risks.
Managed by the Nebraska Department of Natural Resources, the Delbert Boelter Irrigation Dam serves as a key infrastructure for water resource management in the area. With its strategic location along the TR-VERDIGRE CREEK, the dam helps regulate water flow and provides essential irrigation support to local farmers. As climate change continues to impact water availability, ensuring the reliability and safety of structures like this dam becomes increasingly crucial for sustaining agricultural productivity in the region.

Dam Data Reference
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.
