Summary
The dam stands at a height of 30.2 feet and has a storage capacity of 49.6 acre-feet. Situated on TR-Indian Creek, the dam serves as a crucial resource for the surrounding area, providing water for various uses while also mitigating the risk of flooding.
Managed by the NE Department of Natural Resources, Piester Dam is regulated, inspected, and enforced by the state, ensuring its safe operation and maintenance. With a low hazard potential and a condition assessment that is currently not rated, the dam has undergone regular inspections, with the last one conducted in July 2018. Despite its age, Piester Dam continues to play a vital role in water resource management, demonstrating its resilience and importance in the region's infrastructure.
Overall, Piester Dam serves as a testament to the intersection of water resource management and climate resilience. Its strategic location, design features, and state regulations make it a key asset in the area's infrastructure. As water resource and climate enthusiasts, observing the ongoing maintenance and operation of Piester Dam offers insights into the importance of sustainable water management practices and the role of dams in safeguarding communities against natural disasters and ensuring water security for various needs.

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.
