Summary
2, located in Niobrara, Wyoming, is an earth dam constructed in 1965 for the purpose of irrigation along the Bad Land Draw river. Designed by John A. Lambert, this privately owned structure stands at a height of 24 feet, with a hydraulic height of 16 feet and a length of 535 feet. Despite its low hazard potential, the dam is currently assessed to be in poor condition, with a risk assessment rating of moderate (3).
With a storage capacity of 552 acre-feet and a surface area of 51 acres, Bad Land No. 2 plays a crucial role in supporting agricultural activities in the region. However, its poor condition and the lack of recent inspections raise concerns about its long-term reliability and safety. The dam features an uncontrolled spillway with a width of 60 feet and a single slide gate as the outlet structure.
As water resource and climate enthusiasts, it is essential to monitor and address the deteriorating condition of Bad Land No. 2 to ensure the continued efficiency and safety of this irrigation infrastructure. Collaboration between relevant state regulatory agencies, such as the SEO in Wyoming, is needed to implement necessary maintenance and rehabilitation measures to mitigate potential risks and safeguard the surrounding communities and ecosystems.

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.
