Marshall Retention Basin Dam dam
Marshall Retention Basin Dam
The Marshall Retention Basin Dam in North Carolina serves as a crucial piece of infrastructure for flood risk reduction in Catawba County. This concrete dam stands at a hydraulic height of 22 feet and spans a length of 465 feet, with a storage capacity of 12 acre-feet. The dam is state-regulated, inspected, and enforced by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring its structural integrity and safety.
Despite its high hazard potential, the Marshall Retention Basin Dam is deemed to be in satisfactory condition as of the last assessment in June 2020. Emergency action plans are in place, and regular inspections are conducted to mitigate risks and ensure public safety. As a public utility structure, the dam plays a crucial role in managing water resources and protecting surrounding communities from potential flooding events. Climate and water resource enthusiasts can appreciate the significance of this dam in safeguarding the region against natural disasters and the impacts of changing environmental conditions.
With its strategic location and purposeful design, the Marshall Retention Basin Dam stands as a testament to effective flood risk reduction measures in North Carolina. As climate change continues to pose challenges to water resource management, structures like this play a vital role in safeguarding communities and infrastructure. The dedication to maintaining and regulating the dam underscores the commitment to protecting the environment and residents in the area, making it a noteworthy site for water resource and climate enthusiasts to study and appreciate.

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 Marshall Retention Basin Dam
Where does the data for Marshall Retention Basin 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 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.
