Summary
Built in 1963 by USDA NRCS, this dam serves primarily for flood risk reduction along TR-Foster Creek. With a height of 25 feet and a length of 750 feet, Pleasant Valley No 3 has a storage capacity of 326 acre-feet, making it a vital structure in the area's water resource management.
The dam's spillway type is uncontrolled with a width of 2 feet, and it features slide (sluice gate) outlet gates for water release. Despite being rated with a high hazard potential, the dam's condition assessment is fair as of the last inspection date in December 2020. It is regulated by the Louisiana Department of Transportation and Development, with state permitting, inspection, and enforcement in place to ensure its continued safety and functionality for flood risk reduction and recreational purposes in Washington Parish.
Overall, Pleasant Valley No 3 plays a crucial role in mitigating flood risks in the region, with a moderate risk assessment score of 3. While it poses a high hazard potential, regular inspections and maintenance efforts are being carried out to ensure the dam's structural integrity and public safety. As an essential component of water resource management, this earth dam continues to serve its purpose effectively in safeguarding the community against potential flooding events along TR-Foster Creek.

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.
