Summary
This earth dam stands at a height of 25 feet, with a hydraulic height of 23 feet and a structural height of 26 feet. It serves the primary purpose of flood risk reduction and has a storage capacity of 202 acre-feet, with a maximum discharge of 440 cubic feet per second. The dam is situated on TR-LODGEPOLE CREEK and is regulated by the Nebraska Department of Natural Resources.
With a low hazard potential and satisfactory condition assessment as of August 2020, Nelson Dam 755 plays a crucial role in managing water resources in the area. Its normal storage capacity is 18 acre-feet, covering a surface area of 6 acres and draining a 2.3 square mile drainage area. The dam has not been modified in recent years and is not managed by the US Army Corps of Engineers, indicating its significant role in local water management outside federal regulations.
As a key structure for flood risk reduction, Nelson Dam 755 stands as a testament to effective private ownership and management of water resources. With its capacity to mitigate flood impacts and regulate water flow, this dam showcases the importance of private investments in infrastructure for climate resilience. The dam's location, design, and operational history highlight its essential role in safeguarding communities and ecosystems in Kimball, Nebraska, demonstrating the value of local water resource management efforts.

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.
