Summary

This private-owned Earth dam stands at a height of 28 feet and has a hydraulic height of 25 feet, with a length of 341 feet. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.

With a normal storage capacity of 19 acre-feet and a maximum storage of 29 acre-feet, Mccreary Dam plays a crucial role in managing the water resources in the area. The dam's spillway, of uncontrolled type, has a width of 10 feet. Despite its moderate risk classification (3), the dam has not been assigned a DSAC assessment date, and risk management measures are not specified. The dam poses no state jurisdiction or regulation, with no state permitting, inspection, or enforcement in place.

Water resource and climate enthusiasts can appreciate the significance of Mccreary Dam as a key infrastructure for managing water flow and ensuring grade stability in the region. The dam's strategic location in Putnam County, Missouri, underscores its importance in safeguarding the surrounding area from potential flooding events. As a privately owned structure, Mccreary Dam stands as a testament to the collaboration between private entities and the state in ensuring the resilience of water infrastructure systems.

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.
