Summary

Completed in 2002, this earth dam stands at a height of 24 feet and spans a length of 480 feet. With a storage capacity of 104 acre-feet and a surface area of 6.1 acres, the dam serves as a vital resource for the surrounding area.

Regulated by the Iowa DNR, Morgan Dam is classified as having a low hazard potential with a moderate risk assessment rating. While not currently rated for condition assessment, the dam remains under state jurisdiction and is subject to regular inspection, permitting, and enforcement. The spillway, measuring 2 feet in width, is uncontrolled in nature, ensuring the safe release of excess water. Despite its relatively low hazard potential, Morgan Dam plays a crucial role in water resource management and climate adaptation efforts in the region.

As a key component of the local water infrastructure, Morgan Dam provides essential fire protection, stock, and recreational opportunities for the community. With its strategic location on TR- Honey Creek and its significant storage capacity, the dam serves as a valuable asset for managing water resources and mitigating the impacts of climate change in the area. Through ongoing monitoring and maintenance, Morgan Dam continues to support the region's water needs while upholding safety and regulatory standards set by the state of Iowa.

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.
