About this dam

Kay Thompson Dam

Kay Thompson Dam, located in Shreveport, Louisiana, is a privately owned structure that serves primarily for recreation purposes. Built in 1945, this earth dam with a buttress core stands at a height of 18.5 feet and spans 950 feet in length, impounding a maximum storage capacity of 412 acre-feet of water from the TR-Boggy Bayou stream. The dam's normal storage capacity is 356.8 acre-feet, covering a surface area of 22.3 acres within a drainage area of 2 square miles.

Managed by the Louisiana Department of Transportation and Development, Kay Thompson Dam has a low hazard potential and is currently rated in fair condition following its last inspection in September 2016. With an uncontrolled spillway width of 35 feet, the dam poses a moderate risk level (3) according to the risk assessment. Despite not having associated locks or outlet gates, the dam remains a popular spot for recreational activities and scenic enjoyment in the Caddo County area.

Overall, Kay Thompson Dam stands as a testament to both engineering ingenuity and environmental stewardship, providing a safe and enjoyable space for water resource and climate enthusiasts to appreciate the beauty of Louisiana's natural landscapes while respecting the importance of dam safety and maintenance protocols.

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 Kay Thompson Dam

Where does the data for Kay Thompson 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
