Summary
Standing at a height of 54 feet and stretching 400 feet in length, this dam was completed in 1974 and serves the primary purpose of controlling the flow of the TR-OWL CREEK river or stream. With a storage capacity of 60 acre-feet and a drainage area of 32 square miles, this dam plays a crucial role in managing water resources in the area.
The dam's spillway, categorized as uncontrolled, has a width of 4 feet, and the structure is regularly inspected to ensure its safety and effectiveness. With a hazard potential rated as high, the dam's condition has been assessed as satisfactory as of December 2007. While it has not been modified in recent years, the dam is equipped with emergency action plans and contacts to mitigate any potential risks. Overall, Owl Creek Estates Dam #2 is a vital component in managing water resources in the region while safeguarding against potential hazards.
Managed by the DAM AND RESERVOIR SAFETY PROG of the state of Missouri, this dam falls under state regulation, permitting, inspection, and enforcement. As a key component in the local water resource infrastructure, Owl Creek Estates Dam #2 continues to play a crucial role in maintaining water quality and quantity in the area. With a moderate risk assessment rating, efforts are ongoing to ensure the dam's safety and functionality for the benefit of the community and surrounding environment.

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.
