Summary
The earth dam stands at a height of 37 feet and has a length of 273 feet, with a storage capacity of 37 acre-feet and a surface area of 2.2 acres. The dam is regulated by the Iowa Department of Natural Resources and is inspected, permitted, and enforced by state agencies to ensure its safety and functionality.
Despite being classified as low hazard potential with a moderate risk assessment score of 3, Maudsley Dam has not been rated for its condition assessment. The dam is equipped with an uncontrolled spillway and is situated on the TR-Purcell Creek, contributing to its drainage area of 0.05 square miles. The dam's location in Kossuth County, Iowa, makes it a vital resource for water management and conservation efforts in the region, as it helps provide water for firefighting, livestock, and recreational fishing purposes.
Overall, Maudsley Dam serves as a crucial water resource for the community of Irvington, Iowa, offering essential services for fire protection and agricultural needs. With its state-regulated status and regular inspections, the dam ensures the safety and sustainability of its operations while contributing to the overall water management efforts in the area. For water resource and climate enthusiasts, Maudsley Dam stands as a noteworthy example of a privately-owned structure that plays a significant role in local water conservation and management efforts.

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.
