Summary
Completed in 1980, this earth dam stands at a height of 36 feet and spans a length of 1000 feet, with a storage capacity of 121 acre-feet and a surface area of 17 acres. The dam is regulated, permitted, and inspected by the DAM AND RESERVOIR SAFETY PROG, ensuring its safety and functionality.
With a high hazard potential and a moderate risk assessment rating, Lost Creek B-2 is classified as a crucial infrastructure for flood control in the region. Its satisfactory condition assessment as of February 2011, along with regular inspections every two years, demonstrates its reliability in safeguarding the surrounding area from potential inundation. Equipped with a slide (sluice gate) outlet gate and an uncontrolled spillway, the dam is well-equipped to manage high discharge levels up to 851 cubic feet per second.
Lost Creek B-2 stands as a testament to effective water resource management and climate resilience efforts in Missouri, serving as a critical asset for flood risk reduction along the Lost Creek watershed. With its strategic design, sturdy construction, and ongoing regulatory oversight, this dam plays a pivotal role in protecting the local community and environment from the impacts of extreme weather events and potential flooding scenarios.

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.
