Summary
Completed in 1960, this earth dam stands at a height of 13.4 feet and has a storage capacity of 74.2 acre-feet, with a normal storage level of 5.8 acre-feet. The dam also covers a surface area of 2.5 acres and serves a drainage area of 0.75 square miles.
Although Rasser Dam 8921 has a low hazard potential, its current condition assessment is rated as poor, highlighting the need for maintenance and potential improvements. The dam has been inspected periodically, with the last assessment conducted in April 2017. Despite its condition, the dam continues to serve its primary purpose of flood risk reduction effectively, demonstrating its importance in the region's water resource management.
Managed by the Nebraska Department of Natural Resources, Rasser Dam 8921 is a key infrastructure for the local community. With its strategic location and vital role in protecting against flooding, this dam represents a critical component in the state's water resource and climate resilience efforts. It is essential to ensure that necessary repairs and upgrades are made to maintain the dam's integrity and safeguard the surrounding areas from potential risks.

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.
