Summary
The dam, with a height of 25 feet and a length of 605 feet, serves the primary purpose of Grade Stabilization along T-Lotts Creek. With a storage capacity of 66 acre-feet and a drainage area of 0.19 square miles, the dam plays a crucial role in managing water flow and preventing erosion in the region.
Managed by the Iowa DNR, this earth dam with a soil foundation is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being rated as "Not Rated" in terms of condition assessment, the dam has a low hazard potential and a moderate risk level. While there are no emergency action plans prepared or updated for this site, the dam continues to serve its purpose effectively in mitigating the impacts of flooding and improving water quality in the East Fork Grand River Watershed. Enthusiasts of water resources and climate in the area can appreciate the importance of this structure in protecting the local environment and communities from potential risks associated with water management.

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.
