Summary
Talley is a privately owned dam located in Meade, South Dakota, along the TR CHEYENNE river. Built in 1964, this earth dam stands at a height of 28 feet and has a storage capacity of 259 acre-feet, with a maximum discharge of 3000 cubic feet per second. The dam is under the regulatory jurisdiction of the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state permitting, inspection, and enforcement.
Despite its low hazard potential and current condition being not rated, D. Talley plays a crucial role in water resource management in the region. It is primarily managed by the Natural Resources Conservation Service and falls under the St. Paul District of the US Army Corps of Engineers. With its normal storage capacity of 154 acre-feet, the dam serves as a vital infrastructure for flood control and water supply, highlighting the importance of sustainable management practices and monitoring for climate change resilience.
As a key component of the water infrastructure in South Dakota, D. Talley requires continued attention and maintenance to ensure its functionality and safety. With the potential for risk management measures, emergency action planning, and regular inspections, the dam serves as a critical resource for the local community and underscores the need for proactive measures to address the challenges posed by climate change and evolving water resource demands.

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.
