Summary
The dam stands at a height of 22 feet with a hydraulic height of 21 feet and a length of 518 feet, providing a storage capacity of 65 acre-feet for normal operations. Despite its low hazard potential, the dam's condition assessment in 2016 rated it as poor, highlighting the need for maintenance and potential improvements to ensure its long-term stability.
Managed by the Nebraska Department of Natural Resources, Jones Dam 1770 is subject to state regulation, permitting, inspection, and enforcement to uphold safety standards and mitigate risks. The dam's location in Walton and its association with the Kansas City District of the USACE further underscore its importance in water resource management and climate resilience efforts. While the dam has not undergone significant modifications in recent years, its last inspection in 2016 called for a 5-year inspection frequency to monitor its structural integrity and address any maintenance issues promptly.
Overall, Jones Dam 1770 serves as a vital infrastructure for flood protection in the region, but its current condition warrants attention to ensure its continued effectiveness and safety. With its historical significance dating back to the late 20th century, the dam remains a key component in the state's water resource management strategy, requiring ongoing monitoring and potential rehabilitation efforts to enhance its functionality and longevity in the face of evolving climate challenges.

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.
