Summary
The dam stands at a height of 25 feet and has a length of 465 feet, with a storage capacity of 82 acre-feet and a drainage area of 0.5 square miles. Despite its low hazard potential, the dam's condition assessment is rated as poor as of the last inspection in May 2016.
Situated on TR-Brownell Creek, Janeke Dam plays a crucial role in water resource management in the region, with a maximum discharge capacity of 330 cubic feet per second. While the dam's structural integrity is a concern due to its poor condition assessment, it remains state regulated and inspected by the Nebraska Department of Natural Resources. The dam's location in a rural area underscores its importance for local fire protection, agricultural needs, and ecological support for small fish populations.
Water resource and climate enthusiasts can appreciate Janeke Dam as a vital infrastructure for enhancing community resilience and supporting sustainable water use. The dam's historical significance, combined with its current operational challenges and regulatory oversight, highlights the complex interplay between human activities and natural resources. As efforts to address the dam's poor condition continue, ongoing maintenance and monitoring are essential to ensure the safety and effectiveness of this valuable water management structure in Nebraska's landscape.

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.
