Garner Ww Lagoon #1 dam
Garner Ww Lagoon #1
Garner Ww Lagoon #1, also known as Wrenn Road #1, is a vital water resource located in Wake, North Carolina. This lagoon is owned and regulated by the local government, with the State Regulatory Agency overseeing its operations. Built in 1988, this Earth-type dam has a hydraulic height of 34 feet and a structural height of 36 feet, with a storage capacity of 394 acre-feet. The lagoon covers a surface area of 25 acres and serves the primary purpose of water management.
With a high hazard potential, Garner Ww Lagoon #1 has been deemed to be in satisfactory condition as of its last assessment in November 2019. The dam has a regular inspection schedule, with the last inspection conducted in 2019 and an inspection frequency of every 2 years. As a crucial infrastructure for the region, the lagoon plays a significant role in managing water resources and ensuring the safety of surrounding communities.
Despite its importance, Garner Ww Lagoon #1 does not have associated structures or federal agency involvement. However, with its location near the Swift Creek-Tr river and within the Wilmington District, the lagoon remains a key component of the local water management system. As water resource and climate enthusiasts, understanding the significance of structures like Garner Ww Lagoon #1 is essential for ensuring sustainable water management practices in the face of changing environmental conditions.

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 Garner Ww Lagoon #1
Where does the data for Garner Ww Lagoon #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.
