Summary
Owned by the local government and regulated by the Nebraska Department of Natural Resources, the dam stands at a height of 16 feet with a hydraulic height of 10.32 feet, providing a maximum storage capacity of 90.4 acre-feet and a normal storage of 59 acre-feet. With a low hazard potential and satisfactory condition assessment, the dam offers residents and visitors a safe and enjoyable outdoor experience.
The dam's primary purpose of recreation is evident in its design, an earth dam with stone core and soil foundation, spanning a length of 4400 feet and covering a surface area of 6.55 acres. Despite its modest size, Arnold Dam plays a significant role in water resource management, supporting a drainage area of 0.04 square miles and a maximum discharge of 5 cubic feet per second. With state jurisdiction, permitting, inspection, and enforcement in place, the dam is operated efficiently to ensure public safety and environmental protection.
Representing Congressional District 03 in Nebraska, Arnold Dam is well-maintained with regular inspections and a designated emergency action plan. The dam's location in a rural setting adds to its charm, attracting outdoor enthusiasts and nature lovers alike. As a valuable asset in the region's water infrastructure, Arnold Dam stands as a testament to the importance of sustainable water resource management and climate adaptation efforts in safeguarding our natural environment for future generations.

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.
