About this dam

Long Lake Dam

Long Lake Dam in Louisiana, managed by a private owner, was completed in 1962 for recreational purposes. The earth dam stands at 30 feet high with a storage capacity of 4200 acre-feet. Located in Caddo County, the dam on TR - Kelly Bayou has a low hazard potential and is in fair condition as of the last assessment in 2016. The spillway, with a width of 44 feet, is uncontrolled, and the dam has a maximum discharge of 1125 cubic feet per second.

This picturesque dam, with a surface area of 280 acres and a drainage area of 2.55 square miles, provides a tranquil setting for outdoor enthusiasts. Despite its moderate risk assessment, the dam has been regularly inspected and meets state regulations for operation, maintenance, and enforcement. With its scenic location in Shreveport and recreational opportunities, Long Lake Dam is a valuable water resource for the community, ensuring both safety and enjoyment for visitors.

For water resource and climate enthusiasts, Long Lake Dam serves as a vital infrastructure for water management and recreational activities in Louisiana. With its strategic location and sustainable design, the dam plays a crucial role in maintaining water levels and regulating the flow of TR - Kelly Bayou. As climate change continues to impact water resources, Long Lake Dam stands as a resilient structure, contributing to the conservation and utilization of water 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 Long Lake Dam

Where does the data for Long Lake Dam 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
