Summary
Completed in 1999, this private earth dam serves as a focal point for recreational activities, offering a serene escape for water resource and climate enthusiasts alike. With a structural height of 5.8 feet and a hydraulic height of 6.8 feet, the dam boasts a storage capacity of 146 acre-feet, providing ample water for its 50-acre surface area.
Located in the vicinity of the tributary to Pettis Creek, Lost Lake Woods East Dam plays a critical role in water management and conservation efforts in the region. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition, highlighting the need for ongoing monitoring and maintenance. With a spillway width of 2 feet and an uncontrolled spillway type, the dam ensures safe water release in times of excess inflow, enhancing its overall safety and operational efficiency.
As a cornerstone of the local landscape, Lost Lake Woods East Dam not only enriches the surrounding ecosystem but also provides a valuable recreational resource for residents and visitors. With its tranquil waters and idyllic setting, this earth dam represents a harmonious blend of human innovation and environmental stewardship, inviting all who appreciate the beauty and resilience of our natural world to explore and enjoy its splendor.

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.
