Northwest Water Treatment Plant Dam #1 dam
Northwest Water Treatment Plant Dam #1
Northwest Water Treatment Plant Dam #1, also known as Swann Wtp Reservoir No. 1, is a crucial structure in Forsyth, North Carolina, serving as a key resource for water supply in the region. Completed in 2003, this earth dam stands at a structural height of 41 feet with a hydraulic height of 37.5 feet, offering a storage capacity of 131 acre-feet. With a primary purpose of water supply, this offstream dam plays a vital role in ensuring the availability of clean water for the community.
Despite being classified as having a high hazard potential, the dam is currently assessed to be in fair condition as of the last inspection in March 2021. The state regulatory agency, NCDEQ, DEMLR, Dam Safety Program, oversees the permitting, inspection, and enforcement of regulations for this dam. The emergency action plan (EAP) for the dam was last revised in February 2015, and the structure is subject to regular inspections every two years to ensure its integrity and safety for the surrounding area.
Located in the Huntington District and owned by the local government, Northwest Water Treatment Plant Dam #1 stands as a critical infrastructure for water resource management in North Carolina. With its significant storage capacity, this dam plays a pivotal role in supplying water to the community while adhering to state regulations and safety protocols to mitigate risks associated with its high hazard potential.

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.

About Northwest Water Treatment Plant Dam #1
Where does the data for Northwest Water Treatment Plant Dam #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.
