About this dam

Shelter Lake Dam

Shelter Lake Dam, located in De Soto, Louisiana, is a private dam regulated by the Louisiana Department of Transportation and Development. Standing at a height of 28 feet and with a hydraulic height of 20 feet, this earth-type dam serves primarily as a fish and wildlife pond for recreational purposes. With a maximum storage capacity of 848.4 acre-feet and a normal storage capacity of 606 acre-feet, Shelter Lake Dam covers a surface area of 30.3 acres and drains an area of 0.35 square miles.

This low-hazard dam, with a fair condition assessment as of November 2017, features an uncontrolled spillway with a width of 50 feet. Despite its moderate risk level, the dam has not undergone any modifications in recent years and is subject to inspection every five years. The risk assessment for Shelter Lake Dam indicates a rating of 3 on a scale of 1 to 5, highlighting the importance of ongoing monitoring and potential risk management measures to ensure the safety and integrity of this vital water resource. Enthusiasts of water resources and climate in the area will find Shelter Lake Dam to be a fascinating structure that plays a crucial role in supporting local fish and wildlife populations and providing recreational opportunities for the community.

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 Shelter Lake Dam

Where does the data for Shelter 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.
