Summary

The dam stands at 33 feet high and stretches 340 feet in length, providing a storage capacity of 40 acre-feet. With a surface area of 2.9 acres and serving a drainage area of 0.1 square miles, Hulme Dam plays a critical role in managing water resources in the area.

Managed by the Iowa Department of Natural Resources, Hulme Dam has a low hazard potential and is currently rated as not assessed for condition. The dam's spillway, categorized as uncontrolled, has a width of 1 foot, ensuring proper water discharge during high flow events. Despite being a private structure, the dam is subject to state regulations, inspections, and enforcement, highlighting the importance of ensuring its safety and functionality for both water resource management and public safety.

With its strategic location on the TR-Soap Creek, Hulme Dam contributes to water conservation efforts in the region and provides valuable ecosystem services. As climate change continues to impact water resources, structures like Hulme Dam play a crucial role in mitigating risks of flooding, ensuring water availability, and supporting local biodiversity. As water resource and climate enthusiasts, understanding the significance of dams like Hulme Dam is essential for promoting sustainable water management practices and resilience in the face of a changing climate.

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.
