Summary
Built in 1964 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along TR-Foster Creek. With a height of 25 feet and a length of 4000 feet, Pleasant Valley No 4 has a storage capacity of 325 acre-feet and covers a surface area of 30 acres.
The dam is regulated and inspected by the Louisiana Department of Transportation and Development (LA DOTD) to ensure its structural integrity and safety. It features a slide (sluice gate) outlet gate and an uncontrolled spillway with a width of 3 feet. Despite being assessed as in fair condition during the last inspection in December 2020, Pleasant Valley No 4 has a high hazard potential and a moderate risk assessment rating. With its critical role in flood risk reduction and potential for recreational use, this dam is a significant water resource structure in Washington Parish, Louisiana.
Water resource and climate enthusiasts interested in the infrastructure of Pleasant Valley No 4 will find this dam a compelling subject of study due to its historical significance, design features, and management by the Natural Resources Conservation Service. With its location in a diverse ecosystem and its impact on flood control and wildlife habitat, Pleasant Valley No 4 offers valuable insights into the intersection of water management, environmental conservation, and community safety in Louisiana's water resources landscape.

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.
