Summary
This earth dam, standing at a height of 39 feet and a length of 593 feet, holds a maximum storage capacity of 800 acre-feet and normal storage of 592 acre-feet. Situated on the E Branch of Verdigris Creek, the dam covers a surface area of 54 acres and has a drainage area of 11.5 square miles.
With a low hazard potential and satisfactory condition assessment as of May 2019, Grove Lake Dam is regularly inspected by the Nebraska Department of Natural Resources. The dam is equipped with outlets gates and has a maximum discharge capacity of 2000 cubic feet per second. While there are no associated locks or spillways, the dam's structure, primarily made of earth with stone core, remains stable and secure for recreational use and water resource management in the area.
Located in Antelope County, Nebraska, Grove Lake Dam is a vital water resource for the region, offering recreational opportunities and water storage capacity. Managed by the state and inspected for safety on a regular basis, the dam plays a crucial role in maintaining the ecological balance of the area while providing a picturesque setting for outdoor enthusiasts and climate advocates to enjoy.

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.
