Summary
Built in 1936, this earth dam stands at 29 feet high and stretches 742 feet in length, with a storage capacity of 390 acre-feet. It is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is equipped for state permitting, inspection, and enforcement.
Despite its age, England No.2 has a low hazard potential and has not been rated for its condition assessment. It is not part of the US Army Corps of Engineers (USACE) system and does not have a designated emergency action plan in place. The dam's maximum discharge capacity is 2048 cubic feet per second, serving a vital role in managing water resources in the area.
For water resource and climate enthusiasts, England No.2 presents an intriguing case study of a historic dam in the heart of South Dakota. Its location, design, and regulatory oversight offer valuable insights into the intersection of water management, infrastructure resilience, and environmental stewardship in the region. As discussions around sustainable water practices and climate adaptation continue to evolve, England No.2 serves as a reminder of the importance of maintaining and monitoring aging infrastructure to ensure the safety and security of communities and ecosystems.

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.
