Summary
This private dam, completed in 1960, is classified as an earth dam with a height of 13 feet and a length of 272 feet. With a storage capacity of 95 acre-feet and a normal storage level of 8 feet, this dam plays a crucial role in managing water resources in the area.
Managed by the Nebraska Department of Natural Resources, Hoffman Dam 679 has low hazard potential and is currently rated as 'Not Rated' in terms of its condition assessment. The dam has undergone inspections every five years, with the most recent inspection taking place in August 2019. While the dam does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, it meets state regulatory requirements for inspection, permitting, and enforcement.
With its key location in Webster County, Nebraska, Hoffman Dam 679 stands as a vital structure for water resource management in the region. Enthusiasts of water resources and climate change will find this dam's design, purpose, and regulatory oversight to be of interest in understanding the intersection of infrastructure, environmental protection, and public safety.

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.
