Summary
With a height of 39 feet and a length of 205 feet, the dam serves multiple purposes including fire protection and creating a small fish pond. The dam is situated on the TR-Mud Creek and has a storage capacity of 50 acre-feet, with a normal storage level of 31 acre-feet.
Managed by the Iowa DNR, the dam is regulated and inspected by state authorities to ensure its safety and compliance with regulations. With a low hazard potential and a moderate risk assessment rating, the dam is considered to be in good condition and poses minimal risk to the surrounding area. Despite being uncontrolled, the spillway width and maximum discharge are not specified in the data.
In the event of an emergency, the dam's Emergency Action Plan (EAP) status and readiness are not specified in the data, but it is important for local authorities and stakeholders to have a thorough plan in place to mitigate any potential risks associated with the dam. Overall, the Stratton Dam plays a crucial role in water resource management and protection in the region, showcasing the importance of maintaining and monitoring such structures for the well-being of the community and the environment.

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.
