Summary
This earth dam stands at a height of 26 feet and has a length of 473 feet, providing a storage capacity of 89 acre-feet and covering a surface area of 5.2 acres. The dam serves the primary purpose of flood risk reduction for the TR- Tuckers Creek stream, with a low hazard potential and a moderate risk assessment rating.
Managed by the Iowa Department of Natural Resources, this site is regulated, permitted, inspected, and enforced to ensure its proper functioning and safety. While the structure has not been rated for condition assessment, it meets state guidelines for emergency action planning and risk management. With no associated structures or locks, the dam features an uncontrolled spillway type with a width of 1 foot. Despite its limited discharge capacity, the dam plays a crucial role in mitigating flood risks in the area and protecting downstream communities.
East Fork Grand River Watershed Site E-44 stands as a testament to collaborative efforts between local government entities, the NRCS, and regulatory agencies in safeguarding water resources and managing climate-related risks. As a vital infrastructure in the Rock Island District, this earth dam exemplifies the importance of proactively addressing flood hazards and ensuring the resilience of watersheds in the face of changing environmental conditions. With ongoing monitoring and management practices in place, this site remains a key component in the overall water resource management strategy for the region.

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.
