Summary
Managed by a private owner, the dam stands at a height of 7 feet with a structural length of 325 feet. With a maximum storage capacity of 68 acre-feet and a normal storage capacity of 19 acre-feet, Gross Dam 2 plays a crucial role in managing water resources in the area.
The dam, designed by USDA NRCS, is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam's condition assessment is currently not rated. With a drainage area of 0.5 square miles and a maximum discharge capacity of 430 cubic feet per second, Gross Dam 2 serves as an important asset for water management and conservation efforts in the region.
Even though Gross Dam 2 may not be the largest or most high-profile dam, its significance lies in its multifaceted purposes and its role in protecting the local community from fire hazards and providing water for livestock and fish. As climate change continues to impact water resources, dams like Gross Dam 2 play a critical role in ensuring water security and resilience in the face of evolving environmental challenges.

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.
