Summary
This dam on the TR-HAT CREEK river has a height of 23 feet and a length of 500 feet, providing a storage capacity of 55 acre-feet for water resource management. With a low hazard potential and a condition assessment of "Not Rated", Fishko Dam #3 serves as a vital infrastructure for maintaining water levels and preventing floods in the region.
Managed by the South Dakota Department of Environment and Natural Resources, Fishko Dam #3 is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. While the dam has not been rated for its condition, its primary purpose is to control water flow and storage, with a maximum discharge capacity of 1100 cubic feet per second. The dam's location in a rural area with limited associated structures highlights its importance in managing water resources and mitigating potential risks during extreme weather events.
As a key component of water resource management in the region, Fishko Dam #3 plays a crucial role in safeguarding against floods and ensuring sustainable water storage. With its historical significance dating back to 1945, this earth dam continues to serve the community by regulating water levels and protecting the surrounding areas from potential hazards. Enthusiasts of water resources and climate will appreciate the role of Fishko Dam #3 in maintaining the balance of water flow and storage in Fall River, South Dakota.

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.
