North Ridge Number 1 Dam dam
North Ridge Number 1 Dam
North Ridge Number 1 Dam, also known as North Brandon Estates, is a privately owned earth dam located in Rankin County, Mississippi. Built in 2002 by Harris and Steed Engineers, this dam spans 500 feet in length and stands at a height of 18 feet, with a primary purpose of providing recreational opportunities for the community. The dam is situated on Brush Creek and has a storage capacity of 228 acre-feet, making it an important water resource in the area.
With a high hazard potential and a satisfactory condition assessment as of May 2020, North Ridge Number 1 Dam is regulated by the Mississippi Department of Environmental Quality, ensuring compliance with safety standards and inspection requirements. The dam features an uncontrolled spillway and has a maximum discharge capacity of 1515 cubic feet per second, serving as a vital structure for flood control and water management in the region. Despite its moderate risk assessment, the dam remains a key asset for recreation and water resource management in Rankin County.
As a significant part of the local water infrastructure, North Ridge Number 1 Dam plays a crucial role in maintaining the safety and stability of the surrounding area. With its strategic location and design features, this dam serves as a valuable resource for both recreation and environmental conservation, highlighting the importance of sustainable water management practices in the face of changing climate conditions.

About North Ridge Number 1 Dam
Where does the data for North Ridge Number 1 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 below 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.

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.
