Summary
Constructed in 2006 by the USDA NRCS, this earth dam stands at a height of 25 feet and stretches 490 feet in length. With a storage capacity of 77 acre-feet, this dam serves to mitigate flood risks in the area, particularly along the TR- Lotts Creek.
Managed by the Iowa DNR, this dam is regulated and inspected regularly to ensure its effectiveness in reducing flood hazards. Despite being rated as having a low hazard potential, its risk assessment indicates moderate risk. While the condition assessment is currently labeled as "Not Rated," efforts are ongoing to monitor and maintain the dam's functionality in the face of changing climate conditions and increasing water resource challenges.
Water resource and climate enthusiasts will find East Fork Grand River Watershed Site D-82 to be an important infrastructure contributing to flood resilience in the region. Its construction and maintenance highlight the collaborative efforts between local government agencies, the USDA NRCS, and the Iowa DNR to protect communities and water resources from the impacts of extreme weather events. As climate change continues to pose threats to water management, the role of such dams in mitigating flood risks becomes increasingly crucial for sustainable development and environmental stewardship.

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.
