Summary
Boke No.1 is a privately owned earth dam located in Meade, South Dakota, along the TR CHEYENNE river. Completed in 1944, this dam stands at a height of 27 feet and has a storage capacity of 184 acre-feet. It serves the primary purpose of regulating water flow and storage, with a low hazard potential and a current condition assessment of 'Not Rated'.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), G. Boke No.1 is subject to state regulation, permitting, inspection, and enforcement. Despite its age, the dam remains in good standing, with no significant modifications or inspections recorded in recent years. The surrounding area is considered low-risk in terms of potential hazards, with emergency preparedness and risk assessment measures yet to be fully detailed.
With a designated congressman and federal agencies not directly involved in its ownership or management, G. Boke No.1 stands as a testament to effective private dam operation and maintenance. Its location within the St. Paul District and close monitoring by state authorities ensure the safety and integrity of this essential water resource infrastructure in South Dakota.

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.
