Summary
Completed in 1994, this earth-type dam stands at a height of 23 feet and has a storage capacity of 97 acre-feet, with a normal storage level of 77 acre-feet. Situated on the tributary of South Chapelle Creek, Krull Dam plays a key role in managing water flow and storage for the surrounding area.
Despite being privately owned, Krull Dam is subject to state regulation, with the South Dakota Department of Environment and Natural Resources overseeing its permitting, inspection, and enforcement. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. While the dam does not have a designated primary purpose listed, its construction and operation are crucial for water management and conservation efforts in the region. With a maximum discharge capacity of 1000 cubic feet per second, Krull Dam plays a significant role in flood control and water supply management.
Although the dam has not been evaluated for its emergency action plan or risk management measures, its presence is essential for maintaining water resources in the area. With its strategic location and design, Krull Dam stands as a testament to the importance of effective water infrastructure for climate resilience and resource sustainability in South Dakota.

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.
