Summary
It was completed in 1936 and serves as a vital structure for managing water resources in the area. The dam has a storage capacity of 126 acre-feet and a maximum discharge of 480 cubic feet per second, making it a crucial component for flood control and water supply in the region.
Despite being classified as having a low hazard potential, England #5 is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, permitting, and enforcement measures. While the dam's condition assessment is currently rated as "Not Rated," its primary purpose and associated structures are not specified in the data. Additionally, it is interesting to note that the dam is not owned or funded by any federal agency, indicating its significance as a privately managed water resource infrastructure.
Overall, England #5 plays a crucial role in water management and climate resilience in the area, highlighting the importance of private ownership in maintaining and regulating essential water infrastructure. As a key feature of the TR ROUND UP CREEK OFFSTREAM system, this Earth-type dam serves as a testament to the collaborative efforts between private owners and state regulatory agencies in ensuring the safety and efficiency of water resources 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.
