S-33 dam
S-33
S-33, located in Broward County, Florida, along the North Fork New River, is a state-regulated dam completed in 1954 for flood risk reduction and irrigation purposes. The dam stands at a height of 20 feet with a structural height of 12 feet and a length of 71 feet, providing a storage capacity of 84 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," S-33 has not undergone recent inspection or maintenance, suggesting a need for further evaluation to ensure its continued effectiveness and safety.
Despite its age, S-33 continues to play a crucial role in managing water resources in the area, with a maximum discharge capacity of 620 cfs. However, the lack of recent inspection data and condition assessment raises concerns about the dam's current state and readiness for potential emergencies. With the dam's emergency action plan status unknown and no risk assessment or management measures in place, there is a need for increased monitoring and maintenance to mitigate any potential risks associated with its operation and structural integrity.
As a key structure in the flood risk reduction system along the North Fork New River, S-33's importance in water resource management cannot be understated. With its location in a highly populated area and the potential for significant impacts in the event of a failure, it is essential that comprehensive assessments, inspections, and emergency preparedness measures are implemented to safeguard both the dam and the surrounding community. Efforts to improve the dam's condition rating, update emergency action plans, and enhance risk management practices are crucial steps in ensuring the long-term resilience and effectiveness of S-33 in the face of evolving climate challenges.

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 S-33
Where does the data for S-33 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 Low 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.
