Marston-La169 Dam dam
Marston-La169 Dam
Marston-La169 Dam, also known as Lake Vivian, is a privately owned structure located in Greenwood, Louisiana. Built in 2017, this earth dam stands at a height of 20 feet and serves primarily as a water supply resource. With a storage capacity of 685 acre-feet, the dam covers a surface area of 51.1 acres and has a drainage area of 0.91 square miles.
Managed by the Louisiana Department of Transportation and Development, the Marston-La169 Dam boasts a low hazard potential and a fair condition assessment as of April 2019. The dam features an uncontrolled spillway with a width of 30 feet and a maximum discharge capacity of 60 cubic feet per second. Despite its moderate risk level, the dam has undergone regular inspections every 5 years to ensure its structural integrity and safety for surrounding communities.
Water resource and climate enthusiasts will appreciate the strategic location and design of the Marston-La169 Dam, which plays a crucial role in providing water supply to the area. With its efficient management and regulatory oversight, this dam serves as a vital infrastructure for maintaining water resources and mitigating potential risks associated with flooding and water scarcity in Caddo County, Louisiana.

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 Marston-La169 Dam
Where does the data for Marston-La169 Dam 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 Low 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.
