Summary

Built in 1966, this Earth type dam stands at a height of 28 feet and has a storage capacity of 135 acre-feet. It serves the primary purposes of recreation and water supply, offering a surface area of 9 acres and normal storage of 42 acre-feet.

Situated on the TR-East Fork Elm Branch river, Blackburn Pond provides a serene setting for recreational activities such as fishing, boating, and wildlife observation. Despite its high hazard potential, the dam's condition assessment is currently not rated, with the last inspection dating back to July 1980. While the dam is not regulated by the state and has no enforcement or inspection measures in place, its importance for water supply and recreation underscores the need for ongoing monitoring and maintenance.

With its picturesque location and potential for outdoor enjoyment, Blackburn Pond (Mononame 209) offers a valuable resource for water and climate enthusiasts in Saline County, Missouri. As a privately owned structure, it provides a peaceful retreat for residents and visitors alike, showcasing the intersection of human-made infrastructure with natural landscapes. While the dam's condition assessment and hazard potential raise some concerns, its historical significance and recreational value make it a noteworthy feature of the local water system.

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.
