Summary
Completed in 1970, this structure stands at a height of 30 feet and has a hydraulic height of 27.2 feet, with a storage capacity of 29.7 acre-feet. Despite its low hazard potential, the dam is currently in poor condition, as indicated by a recent assessment in April 2020.
Operated under the jurisdiction of the Nebraska Department of Natural Resources, Knigge Dam - East plays a crucial role in managing water resources in the area, specifically along TR-Pishel Creek. The dam's design, featuring a stone core and soil foundation, underscores its importance in irrigation practices within the region. With a drainage area of 0.31 square miles and a maximum discharge capacity of 57 cubic feet per second, the dam serves as a vital component in sustaining agricultural activities in the surrounding area.
While Knigge Dam - East serves as a valuable asset for water management and agricultural needs, its current condition raises concerns about its long-term sustainability and effectiveness. With ongoing inspections and potential improvements, there is an opportunity to enhance the dam's functionality and ensure its continued contribution to the local water resource management efforts.

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.
