Summary
Completed in 1965, this dam stands at a height of 34 feet with a structural height of 38 feet and a length of 550 feet. It has a storage capacity of 419 acre-feet and serves the primary purpose of flood risk reduction in the area. The dam is state-regulated and inspected, with the Nebraska Department of Natural Resources overseeing its operation and enforcement.
Situated in SES5T14R3W, Jones Creek 1-A is part of the TR-Clear Creek watershed and falls under the jurisdiction of the Kansas City District of the US Army Corps of Engineers. With a drainage area of 1.1 square miles, this dam has a low hazard potential and is in satisfactory condition as of the last assessment in June 2016. Although no spillway type or width is specified, the dam is equipped with outlet gates and has a maximum discharge capacity of 700 cubic feet per second. Despite its age, Jones Creek 1-A continues to play a crucial role in mitigating flood risks and protecting the surrounding area.
Overall, Jones Creek 1-A serves as a vital infrastructure component in the water resource management system of Polk County, Nebraska. With its strategic location and design, this dam provides essential flood protection while maintaining a low hazard potential. As climate change impacts water resources, the effectiveness of structures like Jones Creek 1-A becomes increasingly important in safeguarding communities and ecosystems from the threats of flooding and water-related disasters.

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.
