Summary

Completed in 1995 for flood risk reduction purposes, this dam stands at a height of 35 feet and has a structural height of 43 feet, with a length of 740 feet. It has a storage capacity of 281 acre-feet and is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement in place.

The dam has a significant hazard potential but has been assessed as satisfactory in condition as of June 2018. It is regularly inspected every three years to ensure its safety and functionality. The dam's primary purpose is flood risk reduction, serving to protect the surrounding area from potential flooding events. With a maximum discharge capacity of 1776 cubic feet per second, this structure plays a crucial role in managing water resources in Cass County, Nebraska.

Located within the Kansas City District and Congressional District 01 of Nebraska, Weeping Water Creek 2-A is an essential part of the region's water infrastructure. With its stone core and soil foundation, this dam symbolizes the efforts to mitigate flood risks and protect local communities from water-related disasters. Climate enthusiasts and water resource experts can appreciate the engineering and regulatory measures that go into ensuring the safety and effectiveness of such critical infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
