Summary
Completed in 1972, this earth dam serves multiple purposes including flood risk reduction and other water resource management objectives. With a maximum storage capacity of 85.8 acre-feet and a normal storage capacity of 26.6 acre-feet, the dam plays a crucial role in regulating the flow of the TR-S BR Point of Rocks Creek.
Managed by the Nebraska Department of Natural Resources, Henrich Dam is subject to state regulation, inspection, and enforcement to ensure its structural integrity and operational efficiency. Although classified as having a low hazard potential, the dam's condition remains unrated as of the last inspection in April 2020. With a drainage area of 2.23 square kilometers and a surface area of 6.7 hectares, the dam contributes to water resource management in the Alliance area and beyond. Climate and water resource enthusiasts can appreciate the role of Henrich Dam in mitigating flood risks and supporting sustainable water management practices in the region.

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.
