Summary
This private-owned earth dam stands at a height of 34 feet and has a spillway width of 16 feet. With a storage capacity of 19 acre-feet and a drainage area of 288 acres, the dam is designed to handle a maximum discharge of 39 cubic feet per second. Despite its low hazard potential and moderate risk assessment rating, the dam's condition remains unrated, and emergency action plans are yet to be prepared.
Situated along the TR-SO FK NO FK FABIUS R river or stream, Forsythe Dam plays a crucial role in fire protection, stock maintenance, and small fish pond activities in the area. Its stone core and soil foundation contribute to its structural integrity, while its uncontrolled spillway ensures efficient water management during peak flow periods. Although no federal agencies are directly involved in the dam's ownership, funding, design, construction, regulation, or inspection, the dam continues to operate reliably under private management, safeguarding the surrounding community from potential flooding events.
With its strategic location and vital role in water resource management, Forsythe Dam stands as a testament to effective grade stabilization efforts in the region. Despite being unregulated by the state and lacking regular inspections, the dam's functionality and purposeful design demonstrate a commitment to maintaining water quality and ensuring the safety of downstream areas. As climate change continues to impact water resources, dams like Forsythe play a crucial role in mitigating risks and enhancing water security for communities in Missouri and beyond.

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.
