Summary

Constructed in 1964 by the Natural Resources Conservation Service, this earthen dam stands at a height of 26 feet and has a storage capacity of 19 acre-feet. Despite its low hazard potential, the dam remains state-regulated and subject to regular inspection, enforcement, and permitting by the South Dakota Department of Environment and Natural Resources.

With a primary purpose that is not explicitly defined, Jim Schuyler 3 serves as a vital structure in the St. Paul District's water resource management system. Its strategic location and design play a crucial role in flood control and water supply management for the surrounding area. However, the dam's condition assessment is currently listed as "Not Rated," suggesting a need for further evaluation and maintenance to ensure its long-term functionality and safety.

As climate change continues to impact water resources and infrastructure, the presence of dams like Jim Schuyler 3 becomes increasingly important in mitigating the effects of extreme weather events and ensuring a reliable water supply for communities. By staying informed about the regulatory oversight, maintenance needs, and risk management measures associated with dams like Jim Schuyler 3, water resource and climate enthusiasts can contribute to the sustainable management of these critical structures for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
