About this dam

Lake Harris Dam

Lake Harris Dam is a vital structure located in Holt, Alabama, along Yellow Creek. Built in 1929, this arch-type dam serves as a water supply source for the area, with a maximum storage capacity of 3,526 acre-feet. The dam stands at a hydraulic height of 54 feet and a structural height of 58 feet, stretching across 696 feet in length. Despite its age, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.

Managed by the local government, Lake Harris Dam plays a crucial role in water resource management in Tuscaloosa County. The dam has not undergone any major modifications over the years and does not fall under state regulation or inspection. With a primary purpose of water supply, the dam's construction was completed by the Alabama agency in charge, with no federal agency involvement in ownership, funding, design, construction, regulation, inspection, or operations.

Lake Harris Dam may not be a widely recognized structure, but its significance in providing water supply to the community cannot be understated. Its location along Yellow Creek and its relatively low hazard potential make it a valuable asset in the region's water resource infrastructure. As climate change continues to impact water availability and quality, the maintenance and upkeep of dams like Lake Harris will be crucial in ensuring a sustainable water supply for the future.

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 Lake Harris Dam

Where does the data for Lake Harris 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.
