Summary
Built in 1959, this earth dam stands at a height of 30 feet and has a structural height of 32 feet, providing a storage capacity of 178 acre-feet. With a drainage area of 134.4 square miles, this dam plays a significant role in managing water flow and protecting the surrounding area from potential flooding events.
Owned by the local government, Lost Cr Pilot Watershed Dam E-2 is classified as having a significant hazard potential due to its purpose of flood risk reduction. Although not currently regulated by the state, the dam's condition is not rated, indicating a need for further assessment. Despite its moderate risk level, this dam has not undergone recent inspection or maintenance, highlighting the importance of ensuring its structural integrity to effectively mitigate flood risks and protect the community of Elsberry.
With a spillway width of 24 feet and no outlet gates, Lost Cr Pilot Watershed Dam E-2 plays a vital role in managing water flow and reducing flood risks in the area. As climate change continues to impact water resources and increase the frequency of extreme weather events, maintaining and monitoring this dam is essential to safeguarding the community and preserving the natural environment. Further evaluation and risk management measures are needed to ensure the continued effectiveness of this critical infrastructure in the face of evolving climate challenges.

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.
