Roy Martin Lake No. 1 dam
Roy Martin Lake No. 1
Roy Martin Lake No. 1, located in Avoyelles, Louisiana, is a private water resource managed by LA Delta Plantation. This recreational lake, completed in 1968, serves as a serene getaway for water and climate enthusiasts to enjoy activities such as fishing and boating. With a dam height of 16 feet and a storage capacity of 264 acre-feet, the lake offers ample opportunities for outdoor recreation while also serving as a vital water source for the surrounding area.
Despite its low hazard potential, the condition assessment of Roy Martin Lake No. 1 is currently rated as poor, requiring attention to ensure its long-term sustainability. The lake's spillway type is uncontrolled, with a spillway width of 6 feet and a maximum discharge of 90 cubic feet per second. The lake's inspection frequency is set at 5 years, with the last inspection conducted in June 2020. While the risk assessment is moderate, there is a need for enhanced risk management measures to maintain the integrity of the structure and ensure the safety of its surroundings.
With its picturesque location and varied recreational opportunities, Roy Martin Lake No. 1 is a haven for nature lovers and water sports enthusiasts alike. As the primary purpose of this earth dam structure is recreation, it serves as a valuable asset for the community, offering a peaceful retreat and a source of enjoyment for all who visit. As efforts continue to maintain and improve the lake's condition, it remains a vital resource for both leisure and environmental conservation in Avoyelles, Louisiana.
Dam data reference
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 Roy Martin Lake No. 1
Where does the data for Roy Martin Lake No. 1 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.
