S-148 dam
S-148
Located in Miami-Dade, Florida, S-148 is a state-regulated water resource structure designed for flood risk reduction along Black Creek (C-1). Completed in 1962, this dam stands at a height of 20 feet, with a structural height of 14 feet and a length of 118 feet. It has a maximum storage capacity of 2977 acre-feet and a normal storage capacity of 2726 acre-feet, covering a surface area of 149 acres.
Despite its low hazard potential, S-148 is not currently rated for its condition assessment. The dam features uncontrolled outlet gates and has not undergone recent inspections. While its emergency action plan status and risk assessment measures are unclear, the structure remains under state jurisdiction, with permitting, inspection, and enforcement processes in place. With a primary purpose of flood risk reduction, S-148 serves as a vital asset for water resource management in the region.
As an enthusiast in water resources and climate, the details of S-148 offer an intriguing glimpse into the infrastructure supporting flood risk reduction efforts in Miami-Dade, Florida. The structure's historical significance, design specifications, and storage capacities provide valuable insights into the management of water resources in the area. While challenges exist in assessing its current condition and emergency preparedness, S-148 stands as a testament to the ongoing efforts to mitigate flooding and protect the surrounding communities.

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-148
Where does the data for S-148 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.
