Summary

The dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 31 feet and a length of 340 feet, the dam has a storage capacity of 80 acre-feet and covers a surface area of 5.8 acres.

Managed by the Iowa DNR, England Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. The dam has a low hazard potential and a moderate risk assessment rating, highlighting the importance of proper maintenance and management. With its location on TR-Little Soap Creek, the dam plays a crucial role in water resource management and climate resilience efforts in the region.

Despite not being rated for its condition assessment, England Dam remains a key infrastructure for water management in the area. With its uncontrolled spillway and soil foundation, the dam is a vital asset for mitigating floods and providing water storage for various purposes. As water resource and climate enthusiasts, it is essential to monitor and support the maintenance of structures like England Dam to ensure sustainable water management practices for the future.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
