Summary
Completed in 1969, this dam serves as a crucial water resource for the area, providing a storage capacity of 60 acre-feet and a maximum discharge of 400 cubic feet per second. Despite being classified as having a low hazard potential, the dam's condition is currently not rated, highlighting the importance of regular inspections and maintenance to ensure its safety and functionality.
Managed by the Natural Resources Conservation Service, Eastern Grazing Assn No1 is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement mechanisms in place. This dam plays a vital role in water management for the region, contributing to the irrigation of agricultural lands and supporting the local ecosystem. With its strategic location along the TR-MISSONot RatedI stream, the dam helps to mitigate floods and ensures a stable water supply for various stakeholders.
As climate change continues to impact water resources and weather patterns, the maintenance and monitoring of infrastructure like Eastern Grazing Assn No1 are crucial for sustainable water management. By staying vigilant and proactive in addressing potential risks and ensuring proper upkeep, this dam can continue to fulfill its role in supporting the local community and environment. With the support of regulatory agencies and stakeholders, efforts to safeguard and enhance the resilience of this vital water resource will be essential in the face of evolving climate challenges.

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.
