Summary
Built in 1950, this private earth dam serves multiple purposes, including fire protection, stock watering, and creating a small fish pond. With a height of 17.2 feet and a storage capacity of 53.3 acre-feet, the dam plays a crucial role in regulating water flow in the TR-Twin Creek watershed.
Managed by the Nebraska Department of Natural Resources, Schwanz Dam 3565 is classified as having a low hazard potential, indicating its stable condition and low risk of failure. While not currently rated for its condition, the dam undergoes regular inspections to ensure its structural integrity and functionality. With a drainage area of 1.03 square miles and a normal storage capacity of 36.4 acre-feet, the dam provides vital water resources for both agricultural and recreational purposes in the area.
As climate change continues to impact water resources, Schwanz Dam 3565 stands as a crucial infrastructure for water management in the region. With its strategic location and multi-purpose design, the dam serves as a valuable asset for mitigating water scarcity, supporting local agriculture, and enhancing wildlife habitats. As water resource and climate enthusiasts, it is essential to recognize the significance of dams like Schwanz Dam 3565 in sustaining ecosystem health and fostering community resilience in the face of changing environmental conditions.

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.
