Summary
Birkland is a privately owned dam located in Ziebach, South Dakota, along the TR-CHEYENNE river. Built in 1944, this earth dam stands at a height of 14 feet and has a length of 570 feet, providing a maximum storage capacity of 109 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, with a low hazard potential rating.
Despite its age, C. Birkland has not been rated for its condition assessment and lacks emergency action plans and risk management measures. The dam is not owned or funded by federal agencies, and has not been modified or equipped with features such as spillways or locks. Although it meets state permitting and inspection requirements, there are no detailed records of its last inspection date or assessment of its overall risk.
Enthusiasts interested in water resource management and climate adaptation may find C. Birkland intriguing due to its historical significance and potential for future improvements in safety and resilience. With its unique location and characteristics, there is an opportunity to enhance the dam's infrastructure to meet modern standards and better protect surrounding communities and ecosystems from potential hazards.

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.
