About this dam

Montebello Sd Existing Dam

The Montebello Sd Existing Dam, located in Greenville, South Carolina, serves as a crucial structure for flood risk reduction along the TR-LANGSTON CREEK. Built in 1999, this private-owned earth dam stands at a height of 20 feet and has a storage capacity of 60 acre-feet, providing vital protection to the surrounding area. However, recent inspections have noted a poor condition assessment and significant hazard potential, indicating the need for maintenance and risk management measures.

Despite its outdated infrastructure, the Montebello Sd Existing Dam continues to play a vital role in safeguarding the local community from potential flooding events. With a surface area of 4 acres and a normal storage capacity of 45 acre-feet, this dam remains a critical piece of South Carolina's flood risk reduction infrastructure. As the dam is regulated and inspected by the state's DHEC agency, efforts to address its poor condition and mitigate potential risks are underway to ensure its continued effectiveness in protecting the area.

As climate change continues to impact water resources and weather patterns, the Montebello Sd Existing Dam serves as a reminder of the importance of maintaining and updating infrastructure to withstand evolving environmental challenges. With a hazard potential deemed significant, it is crucial for stakeholders to prioritize the upkeep and management of this dam to ensure the safety and resilience of the community it serves. By implementing necessary risk management measures and conducting regular inspections, the Montebello Sd Existing Dam can continue to fulfill its primary purpose of flood risk reduction in the face of a changing climate.

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 Montebello Sd Existing Dam

Where does the data for Montebello Sd Existing 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 Significant 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.
