Summary
Standing at a height of 25 feet, the dam has a storage capacity of 27 acre-feet and covers a surface area of 2 acres. While it poses a low hazard potential, its condition assessment is currently rated as 'Not Rated', with no recent inspection date available.
Managed by the St. Louis District of the US Army Corps of Engineers, Lost Canyon Lakes Dam-Sec 26 East does not fall under state jurisdiction and is not regulated or inspected by state agencies. With no designated spillway and a lack of emergency action plan preparedness, the dam's risk assessment and management measures remain unspecified. Despite its low hazard potential, the dam's condition and safety protocols warrant further evaluation to ensure the protection of surrounding communities and water resources.
For water resource and climate enthusiasts, Lost Canyon Lakes Dam-Sec 26 East represents a unique recreational feature in the area, offering opportunities for fishing and boating. However, the lack of comprehensive risk assessment and emergency preparedness raises concerns about the dam's overall safety and resilience in the face of potential hazards. Continued monitoring and evaluation of the dam's condition and management practices are essential to safeguarding both the environment and the public from any potential risks associated with its operation.

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.
