Summary
Managed by the Natural Resources Conservation Service, this dam has a height of 41 feet and a length of 308 feet, providing a storage capacity of 50 acre-feet and serving a drainage area of 0.25 square miles. The dam is situated on the TR-NISHNABOTNA RIVER and is regulated by the Iowa Department of Natural Resources.
Despite being categorized as having a low hazard potential, the Hound Dog Watershed Site B-4 is considered to have a moderate risk level, with a risk assessment rating of 3. While the dam's condition assessment is not rated, it is regularly inspected by the state agency and meets all necessary regulatory requirements. With its uncontrolled spillway type and a surface area of 3 acres, the dam plays a crucial role in flood risk reduction for the local community of HAMBURG.
As a part of the Omaha District, this dam is a key asset in the region's water resource management infrastructure. With a focus on both public safety and environmental conservation, the Hound Dog Watershed Site B-4 stands as a testament to the collaborative efforts of local government and federal agencies in ensuring the sustainable utilization of water resources in Iowa.

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.
