Summary
Built in 1965, this earth dam spans 930 feet in length and stands at a hydraulic height of 12.1 feet, with a structural height of 13.6 feet. The reservoir has a storage capacity of 105 acre-feet and covers a surface area of 16.5 acres, serving as a critical water resource for the surrounding area. Despite its significant hazard potential, Lake Hiawatha has been assessed as being in satisfactory condition, with a moderate risk level.
Situated on Byrd Creek in the Nashville District, Lake Hiawatha plays a vital role in water management in the region, with a normal storage capacity of 80 acre-feet. The dam features an uncontrolled spillway and is subject to regular inspections by the state regulatory agency, ensuring its safety and integrity. Although the reservoir has no associated structures or outlet gates, it remains a key component of the local water infrastructure, providing both recreational opportunities and essential water supply for the community of Homestead.
With a risk assessment rating of moderate, Lake Hiawatha is closely monitored for any potential safety concerns, with an inspection frequency of twice a year. The reservoir's condition is regularly assessed, and emergency response plans are in place to address any unforeseen events. As a significant water resource in the area, Lake Hiawatha continues to be a focal point for water resource and climate enthusiasts, highlighting the importance of sustainable water management practices in the face of changing climate conditions.

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.
