About this dam

Holland Lake

Holland Lake, also known as Feliciana Lake, is a private fish and wildlife pond located in East Feliciana, Louisiana. Managed by the USDA NRCS, this earth dam was completed in 1972 and stands at a height of 19 feet, with a hydraulic height of 16 feet. With a storage capacity of 142 acre-feet and a surface area of 8 acres, Holland Lake serves various purposes including fire protection, stock, small fish pond, and recreation.

The dam is regulated by the Louisiana Department of Transportation and Development, with state inspection, enforcement, and permitting in place. Despite being classified as having a low hazard potential, the condition assessment in 2016 rated the dam as fair. In terms of risk assessment, Holland Lake falls under the moderate category, with a risk level of 3. With a drainage area of 0.45 square miles and a maximum discharge of 1565 cubic feet per second, Holland Lake remains a crucial water resource for the surrounding area.

Overall, Holland Lake offers a unique blend of recreational opportunities and ecological support within the Woodland community. As a vital fish and wildlife habitat, this privately-owned reservoir plays a significant role in water conservation and management in Louisiana. With its scenic beauty and functional design, Holland Lake stands as a testament to sustainable water resource practices in the region, attracting water resource and climate enthusiasts alike.

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 Holland Lake

Where does the data for Holland 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.
