Summary
Completed in 2003, this Earth dam stands at a height of 26 feet and has a storage capacity of 83 acre-feet. With a low hazard potential and a moderate risk assessment rating, this site plays a crucial role in managing water resources in the area.
Owned and regulated by the State of Iowa, this dam on Tr- Lotts Creek is inspected, permitted, and enforced by the Iowa DNR, ensuring compliance with state regulations. The primary purpose of the structure is grade stabilization, with a surface area of 4.7 acres and a drainage area of 0.24 square miles. While the dam has not been assessed for condition, its risk management measures are in line with guidelines, indicating a commitment to safety and environmental protection.
Despite its remote location in the State of Missouri, East Fork Grand River Watershed Site D-63 plays a vital role in water resource management in the region. With its controlled spillway and soil foundation, this structure serves as a key component in the conservation and preservation of the local ecosystem. As water resource and climate enthusiasts, it is important to recognize the significance of such infrastructure in maintaining the balance of our natural surroundings.

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.
