About this dam

Spanish Lake

Spanish Lake is a picturesque reservoir located in New Iberia, Louisiana, owned and managed by the local government. Built in 1958 by the LA Department of Public Works, this earth dam spans 20,740 feet and stands at a height of 18 feet, providing a serene recreational spot for visitors. The reservoir has a storage capacity of 9,100 acre-feet and covers a surface area of 1,240 acres, offering a tranquil environment for water resource and climate enthusiasts to explore.

Managed by the Louisiana Department of Transportation and Development, Spanish Lake is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and compliance with regulations. The dam's spillway is uncontrolled, with a width of 9 feet, and features vertical lift outlet gates. Despite its low hazard potential and fair condition assessment, the reservoir underwent structural modifications in 1994 to enhance its safety and functionality, reflecting a commitment to maintaining the site for public enjoyment and environmental preservation.

With a moderate risk assessment rating and a drainage area of 2.36 square miles, Spanish Lake offers a blend of recreational opportunities and conservation efforts. Its location along Bayou Teche offstream adds to its allure, attracting visitors to appreciate its natural beauty and engage in outdoor activities. As a vital part of the local landscape, Spanish Lake serves as a valuable resource for the community, highlighting the importance of sustainable water management practices and climate resilience in the region.

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 Spanish Lake

Where does the data for Spanish 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.
