About this dam

Holmes Pond

Holmes Pond in De Soto, Louisiana, is a private water resource that serves multiple purposes, including fish and wildlife conservation, recreation, and water supply. Completed in 2010, this earth dam structure stands at 15 feet high and has a storage capacity of 210 acre-feet. The pond covers a surface area of 28 acres and is fed by TR - Garrison Creek, making it an important habitat for various species of aquatic life.

Despite its low hazard potential and fair condition assessment, Holmes Pond is subject to state regulation and inspection by the Louisiana Department of Transportation and Development. The spillway width of 173 feet ensures that the pond can handle a maximum discharge of 1825 cubic feet per second. The structure was last inspected in October 2016, with a frequency of inspections every 5 years to ensure its safety and functionality. With a risk assessment rating of moderate (3), the pond is considered to have a manageable level of risk.

Overall, Holmes Pond provides a valuable resource for the local community in Longstreet, Louisiana, supporting biodiversity and recreational activities while also serving as a water source. Its well-maintained dam and regulated status demonstrate a commitment to environmental stewardship and public safety, making it a key location for water resource and climate enthusiasts to appreciate and monitor.

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.

FAQ

About Holmes Pond

Where does the data for Holmes Pond 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.

Premium feature

Favorites and alerts are part of Snoflo Premium. Save reservoirs, set storage thresholds, and get push notifications when conditions cross.
