Summary
Built in 1954, this earth dam stands at a height of 12 feet and has a length of 630 feet, providing a storage capacity of 77 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
Situated on the TR-MISSONot RatedI river or stream, Wray & Elaine Hall is under the jurisdiction of the St. Paul District of the US Army Corps of Engineers. While the dam's condition is currently not rated, it has not undergone recent inspections or assessments. Despite its modest storage capacity and low hazard potential, the dam serves an important purpose in managing water resources in the region. Water resource and climate enthusiasts may find Wray & Elaine Hall to be an interesting structure that plays a role in the local ecosystem and water management efforts.
Overall, Wray & Elaine Hall represents a significant component of South Dakota's water infrastructure, with its construction dating back to the mid-20th century. Its location, design, and regulatory oversight highlight the importance of maintaining and monitoring dams for water resource management and public safety. As climate change continues to impact water resources, the management and upkeep of structures like Wray & Elaine Hall will be crucial in ensuring the resilience and sustainability of water systems in the region.

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.
