Summary
The dam stands at a height of 43 feet with a length of 494 feet, providing a storage capacity of 210 acre-feet. Situated on the TR-WHITE BREAST CREEK, the dam is regulated by the Iowa Department of Natural Resources and undergoes state permitting, inspection, and enforcement to ensure safety and compliance.
With a hazard potential rated as low and a moderate risk level, Pleasant Dam has not been assessed for condition but is currently considered not rated. The dam features an uncontrolled spillway and a drainage area of 0.24 square miles, serving as a vital water resource for the local area. Although last inspected in 1977, the dam remains an essential structure for water management and conservation in the region, showcasing the importance of maintaining and monitoring such infrastructure for climate resilience and sustainability.
Despite its age, Pleasant Dam continues to play a crucial role in water storage and management, with a primary focus on fire protection and stock support. With its moderate risk assessment, there is a need for regular monitoring and potential updates to ensure the dam's continued functionality and safety. As water resource and climate enthusiasts, understanding the significance of structures like Pleasant Dam highlights the importance of sustainable water practices and infrastructure maintenance to adapt to changing environmental conditions and protect our communities for future generations.

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.
