Pleasant Valley No 3 dam
Pleasant Valley No 3
Pleasant Valley No 3, also known as Scarborough Creek No 3 or Big Ditch, is a local government-owned earth dam located in Angie, Louisiana. 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.

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.
- 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.
- 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.
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, environmental 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.

About Pleasant Valley No 3
Where does the data for Pleasant Valley No 3 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
