Lost Creek Watershed Dam F-1 Reservoir Report
Last Updated: December 5, 2025
Lost Creek Watershed Dam F-1, also known as the Newton County Structure F-1 Dam, is a critical earth dam designed by the USDA NRCS in 1977 for the primary purpose of debris control along the TR-LOST CREEK in Seneca, Missouri.

Summary
With a height of 31 feet and a length of 450 feet, this dam has a storage capacity of 64 acre-feet and serves as a vital infrastructure in the region for flood mitigation and water resource management.
The dam has a high hazard potential due to its location and design. Despite not being rated for its condition, regular inspections are essential to ensure its structural integrity and functionality. The spillway, with a width of 50 feet, is uncontrolled, allowing for the safe release of excess water during heavy rainfall events. The dam plays a crucial role in protecting the surrounding area from potential flooding and maintaining the overall safety and health of the community.
While the dam has not been modified in recent years, it is important to implement risk management measures and emergency action plans to address any potential hazards and ensure the continued effectiveness of Lost Creek Watershed Dam F-1. With a moderate risk assessment rating, proactive measures and regular maintenance are essential to safeguard the dam and the community it serves.

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.
