Summary
Constructed in 1971 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock retention, and small fish pond management. With a height of 47 feet and a length of 900 feet, the dam holds a normal storage capacity of 1203 acre-feet and covers a surface area of 78.9 acres.
Managed by the Iowa Department of Natural Resources, Heritage Point Lake Dam is regulated, inspected, and enforced to ensure its structural integrity and safety. With a significant hazard potential and a satisfactory condition assessment, the dam underwent its last inspection in May 2018. Despite moderate risk levels, the dam is deemed to meet guidelines for emergency action plans, although further risk management measures may be considered to enhance its resilience to potential threats.
Situated on the TR-South Chariton River, Heritage Point Lake Dam plays a crucial role in water resource management in the region. As a focal point for recreation and wildlife habitat, the dam's presence underscores the importance of sustainable dam operations and maintenance to safeguard its surrounding environment and communities. With ongoing oversight and periodic assessments, Heritage Point Lake Dam continues to be a vital asset for water conservation and climate resilience efforts in Iowa.

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.
