Summary
Standing at a height of 26 feet, with a hydraulic height of 25 feet and a structural height of 28 feet, this earth dam spans 756 feet and has a storage capacity of 140 acre-feet. The dam is primarily constructed of stone core and soil foundation, making it a significant asset in managing water resources in the area.
Maintained by the Nebraska Department of Natural Resources, Huffman Grimm Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safe operation and structural integrity. With a hazard potential classified as "significant" and a fair condition assessment as of May 2019, the dam plays a crucial role in protecting the surrounding area from potential flooding events. Despite its age, Huffman Grimm Dam continues to fulfill its primary purpose of flood risk reduction and remains a key component of water resource management in Banner County, Nebraska.
For water resource and climate enthusiasts, Huffman Grimm Dam represents a fascinating example of engineering ingenuity in harnessing the power of water for the benefit of local communities. Its strategic location, design features, and regulatory oversight highlight the importance of sustainable infrastructure development in mitigating natural hazards and ensuring water security for future generations. As a focal point for water management in the region, this dam serves as a reminder of the critical role that such structures play in safeguarding our environment and enhancing resilience to climate change impacts.

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.
