Summary
Chamberlin, a privately owned dam located in Dewey, South Dakota, was completed in 1966 and stands as an Earth-type structure with a height of 22 feet and a length of 400 feet. Managed by the South Dakota Department of Environment and Natural Resources, this dam has a storage capacity of 81 acre-feet, with a maximum discharge of 1680 cubic feet per second. Despite being rated as having a low hazard potential and not currently assessed for condition, H. Chamberlin plays a crucial role in regulating water flow in the TR-MISSONot RatedI river or stream.
With its strategic location and functionality, H. Chamberlin serves as a vital water resource in the region, contributing to flood control and water supply management. The dam's presence is regulated by the state authorities, ensuring its compliance with safety standards through regular inspections and enforcement measures. While the dam's Emergency Action Plan and risk assessment details are not readily available, its operational capabilities and low hazard potential underscore its importance in maintaining water security and climate resilience in Dewey, South Dakota.
As water resource and climate enthusiasts, understanding the significance of infrastructure like H. Chamberlin is crucial in promoting sustainable water management practices and mitigating the impacts of extreme weather events. By recognizing the role of dams in controlling water flow and safeguarding communities from floods, stakeholders can work towards enhancing the resilience of such structures and ensuring their effective operation for the benefit of both the environment and local inhabitants. H. Chamberlin stands as a testament to the interconnectedness of water resources, climate factors, and infrastructure management, highlighting the need for proactive measures to address evolving challenges in the face of a changing climate.

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.
