Summary
Completed in 2002, this Earth dam serves as a Fish and Wildlife Pond with additional purposes including Grade Stabilization and Recreation. With a height of 25 feet and a length of 480 feet, the dam has a NID storage capacity of 111 acre-feet and a drainage area of 0.55 square miles. The dam's spillway type is uncontrolled with a width of 12 feet, and it has a low hazard potential with a moderate risk assessment rating of 3.
Situated in the Page County of Iowa, the Hatfield Partnership is a key feature in the conservation and management of water resources in the area. The dam contributes to the enhancement of fish and wildlife habitats, while also serving recreational purposes for the local community. Its regulated status ensures that it meets state inspection, permitting, and enforcement requirements, emphasizing its importance in maintaining water quality and ecological balance in the region. The partnership's location near the Trib to Mill Creek in the Kansas City District further highlights its significance in the local hydrological system.
Overall, the Hatfield Partnership stands as a vital component in the sustainable management of water resources in Iowa. With its focus on fish and wildlife conservation, grade stabilization, and recreation, the structure plays a crucial role in promoting environmental stewardship and community engagement. Supported by NRCS design and Iowa DNR regulation, the partnership exemplifies a collaborative effort towards water resource management, ensuring the preservation of ecosystems and the well-being of local wildlife populations.

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.
