Summary
Built in 1937, this private-owned Earth dam stands at a height of 15.3 feet, with a storage capacity of 77.7 acre-feet and a normal storage of 24.6 acre-feet. The dam spans 405 feet in length and covers a surface area of 8.52 acres, providing essential protection to the surrounding areas.
Managed by the Nebraska Department of Natural Resources, Cronk Dam has undergone modifications in 1978 to enhance its seismic resilience. Despite its low hazard potential, the dam has not been rated for its condition as of the last inspection in May 2018. With a designated inspection frequency of 5 years, the dam continues to play a vital role in safeguarding the local community from potential flooding events, further solidifying its importance in water resource and climate management efforts in the region.
Enthusiasts of water resources and climate resilience will find Cronk Dam to be a significant asset in the overall infrastructure for flood risk reduction in Nebraska. Its strategic location, structural design, and storage capacity make it a key player in protecting the surrounding areas from potential inundation. As a privately-owned entity with state regulation and oversight, Cronk Dam stands as a testament to the collaborative efforts between government agencies and private stakeholders in ensuring the safety and sustainability of water resources in the region.

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.
