Summary
This dam, standing at a height of 22 feet with a structural height of 28 feet, has a storage capacity of 454 acre-feet and serves a drainage area of 1.7 square miles. With a low hazard potential and satisfactory condition assessment, Prairie Creek 4 plays a crucial role in mitigating flood risks in the region.
Managed by the local government and regulated by the NE DNR, Prairie Creek 4 is subject to state jurisdiction, permitting, inspection, and enforcement. The dam's spillway type, width, and other specifics are not provided in the data, but its last inspection in March 2018 deemed it satisfactory. With a designated emergency action plan (EAP) status unknown, Prairie Creek 4 serves as a vital infrastructure for flood control in the area, highlighting the importance of ongoing monitoring and maintenance to ensure its continued effectiveness.
Situated in the vicinity of the TR-Prairie Creek, Prairie Creek 4 is a crucial component of the flood risk reduction infrastructure in Nebraska. With its stone core and soil foundation, this dam stands as a testament to the collaborative efforts of the Natural Resources Conservation Service and local authorities in safeguarding the community against potential flood events. As water resource and climate enthusiasts, Prairie Creek 4 serves as a reminder of the vital role that sustainable water management practices play in enhancing resilience and protecting our natural environment.

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.
