Summary
Built in 1937 by the USDA Forest Service, this earth dam stands at 29 feet in height and stretches 978 feet in length, providing a storage capacity of 1357 acre-feet. Situated on Dry Draw, the dam serves as a critical water resource for the surrounding area, supporting fish and wildlife habitats while also mitigating the risk of low hazard potential.
Despite its age, Limestone Butte (Nid) has a moderate risk assessment rating of 3, with a low hazard potential and a not-rated condition assessment. The dam has not been modified in recent years, and its last inspection conducted in 2006 found no significant issues. With a designated emergency action plan and updated contact information, the dam continues to play a vital role in water resource management in Fall River County, South Dakota. As climate change impacts water availability and quality, it is essential to monitor and maintain infrastructure like Limestone Butte to ensure the resilience of our water systems for future generations.

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.
