Summary
This earth-constructed dam, with a height of 19.6 feet and a length of 235 feet, holds a storage capacity of 57.5 acre-feet, catering to the needs of the surrounding area. Located on TR-Twin Creek, the dam's low hazard potential and fair condition assessment make it a reliable resource for water management in the region.
Managed by the Nebraska Department of Natural Resources, Holland East Dam's state-regulated operations include regular inspections to ensure its structural integrity and safety. Despite its modest surface area of 8.4 acres and drainage area of 1.42 square miles, the dam plays a significant role in water resource management and conservation efforts within the community. With its strategic location and historical significance, Holland East Dam remains a key feature in the region's water infrastructure, supporting various agricultural and ecological activities.
For water resource and climate enthusiasts, Holland East Dam presents a fascinating case study in dam engineering and management. Its design, construction, and maintenance exemplify the importance of sustainable water practices and the need for regular inspections and regulatory oversight to ensure public safety and environmental protection. As climate change continues to impact water resources worldwide, structures like Holland East Dam play a crucial role in mitigating risks and adapting to changing conditions, making it a valuable asset in the region's water management portfolio.

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.
