Summary
The dam stands at a height of 25 feet with a structural height of 28 feet and a length of 293 feet, providing a storage capacity of 125 acre-feet. Despite its low hazard potential, the dam's condition is assessed as poor, with the last inspection conducted in May 2017.
Managed by the NE DNR, Pinkerman Dam 1 is regulated, permitted, inspected, and enforced by the state of Nebraska. The dam's primary purpose is irrigation, serving the local agricultural community. With a drainage area of 1.6 square miles and a normal storage capacity of 68 acre-feet, the dam plays a crucial role in water resource management in the region. Although the dam's condition assessment is deemed poor, efforts are being made to ensure its safety and functionality for continued use in the future.
Despite its poor condition assessment, Pinkerman Dam 1 remains a vital water resource infrastructure in Holt, Nebraska, providing irrigation water for agricultural activities in the area. With a history of state regulation and inspections, the dam is essential for water management along the TR-REDBIRD CREEK. As efforts are made to address its poor condition, the dam continues to play a significant role in supporting the local economy and ensuring water availability for the community.

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.
