Summary
Built in 1977 by the Natural Resources Conservation Service, this dam serves the primary purpose of flood risk reduction. With a height of 29 feet and a length of 690 feet, it has a storage capacity of 675 acre-feet, providing essential flood protection for the surrounding area.
The dam has a low hazard potential and has not been rated for its condition. Despite its moderate risk assessment, the dam has not been modified in recent years and is inspected every 5 years. While it does not have a state regulatory agency overseeing it, the dam is under state jurisdiction and is subject to state inspections. In the event of an emergency, the dam has uncontrolled spillways and outlet gates, which may pose challenges in managing floodwaters effectively.
Overall, Grove River WS Str # 33 plays a crucial role in mitigating flood risks in the area, despite its moderate risk assessment. Regular inspections and emergency preparedness are essential to ensure the dam's integrity and effectiveness in protecting the community from potential flooding events. Water resource and climate enthusiasts will find this dam's design and operational details intriguing, highlighting the importance of proper infrastructure for managing water resources in a changing climate.

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.
