Summary
Completed in 2015, this dam stands at a height of 16 feet and has a hydraulic height of 13 feet, with a storage capacity of 120 acre-feet. The lake covers a surface area of 7.5 acres and is fed by an unnamed creek, with a drainage area of 0.16 square miles.
Despite its low hazard potential and fair condition assessment, Dowling Lake #1 is subject to state regulation and inspection by the Louisiana Department of Transportation and Development. The spillway, which is uncontrolled and 40 feet wide, can handle a maximum discharge of 520 cubic feet per second. With a moderate risk assessment rating of 3, the dam has not been assigned a Dam Safety Action Classification (DSAC) date, and there is limited information available on risk management measures in place.
Water resource and climate enthusiasts interested in Dowling Lake #1 will find it to be a picturesque destination for recreational activities, surrounded by the natural beauty of Lincoln Parish in Louisiana. The dam's construction and design details, along with its storage capacity and hydraulic features, make it a noteworthy structure for those studying water resource management and climate impacts on reservoirs. As the dam continues to be monitored and maintained by state authorities, its role in providing both recreational opportunities and flood control in the region remains a focal point for further research and analysis in the field.

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.
