Summary

Built in 1973 by the USDA NRCS, this dam serves primarily for irrigation purposes, with a normal storage capacity of 2400 acre-feet and a maximum storage capacity of 11,000 acre-feet. The dam stands at a height of 71 feet and stretches 2313 feet in length, covering a surface area of 170 acres.

Managed by the local government and regulated by the Arkansas Natural Resources Commission, Cedar-Piney Site 1 poses a high hazard potential due to its proximity to residential areas. While the dam has not been rated for its condition, regular inspections are conducted to ensure its structural integrity. Despite being uncontrolled, the spillway width of this dam is reported as 0, raising concerns for potential overflow during periods of high discharge.

Water resource and climate enthusiasts will find Cedar-Piney Site 1 to be a significant structure in the region, playing a vital role in providing water for irrigation, recreation, and water supply. With its moderate risk assessment and high hazard potential, it underscores the importance of proper maintenance and monitoring to mitigate potential risks and ensure the safety of surrounding communities and the environment.

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.
