Summary

Br. S. Fk. Blackwater Watershed G-34 is a flood risk reduction structure located in Sweet Springs, Missouri. Constructed in 1957, this earth dam stands at a height of 25 feet and has a storage capacity of 40 acre-feet. The dam is designed to mitigate flood risks along the TR-S Fk Blackwater River, serving as a crucial infrastructure for the local community.

Owned by the local government, E. Br. S. Fk. Blackwater Watershed G-34 is not regulated or inspected by the state authorities. With a low hazard potential and a condition assessment that is not rated, the dam plays a vital role in managing water resources in Johnson County, Missouri. Although the dam has not been modified in recent years, its emergency action plan status and risk management measures remain unreported.

As a significant structure in the Kansas City District, E. Br. S. Fk. Blackwater Watershed G-34 highlights the importance of flood risk reduction infrastructure in the region. With its historical significance and role in protecting the local community from potential inundation, this dam serves as a key asset in water resource management and climate resilience efforts in Missouri.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
