Ollie Holm Lake dam
Ollie Holm Lake
Ollie Holm Lake, located in Bossier, Louisiana, is a privately owned reservoir with a primary purpose of recreation and water supply. Constructed in 1955, this Earth dam stands at 24 feet high and spans 1260 feet in length, holding a maximum storage capacity of 175 acre-feet. The lake covers a surface area of 30 acres and is fed by the Red River offstream, making it a vital resource for the surrounding community.
Managed by the Louisiana Department of Transportation and Development, Ollie Holm Lake is regulated and inspected regularly to ensure its structural integrity and safety. Despite being classified as a low hazard potential with fair condition assessment, the reservoir poses a high risk due to its proximity to residential areas. With a maximum discharge of 280 cubic feet per second and no spillway, the lake's risk management measures and emergency preparedness protocols are crucial to mitigate potential disasters and protect the environment.
For water resource and climate enthusiasts, Ollie Holm Lake serves as a valuable case study in reservoir management and risk assessment. Its unique design features and historical significance highlight the importance of sustainable water supply practices and the need for proactive measures to address potential hazards. As a recreational haven and essential water source, this scenic lake embodies the delicate balance between human enjoyment and environmental stewardship in a changing climate.

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 Ollie Holm Lake
Where does the data for Ollie Holm Lake 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.
