About this dam

Mountaintown Creek Ws Str # 1

Mountaintown Creek WS Str # 1 is a state-owned earth dam located in Gilmer, Georgia, built in 1965 for flood risk reduction on Mountaintown Creek. Standing at a height of 81 feet and stretching 520 feet in length, this dam has a storage capacity of 3390 acre-feet and serves a drainage area of 6616 acres. Despite its critical purpose, the dam's condition assessment in 2016 reported it as being in poor condition, with a high hazard potential.

Managed by the Georgia Safe Dams Program, Mountaintown Creek WS Str # 1 is subject to state regulation, inspection, and enforcement. The dam's spillway is uncontrolled, and it has an uncontrolled outlet gate. Although the risk assessment indicates a moderate risk level, the dam's poor condition and high hazard potential highlight the need for timely maintenance and potential rehabilitation to ensure its continued effectiveness in flood risk reduction.

As an important structure in the area, Mountaintown Creek WS Str # 1 serves as a critical flood control measure on Mountaintown Creek. With its historical significance and impact on the local community, efforts to address its poor condition and high hazard potential are essential to safeguarding public safety and protecting the surrounding environment from potential flooding events.

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 Mountaintown Creek Ws Str # 1

Where does the data for Mountaintown Creek Ws Str # 1 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 High 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.
