Swfwmd Magdelene Control Structure #3 dam
Swfwmd Magdelene Control Structure #3
Swfwmd Magdelene Control Structure #3, also known as Hil27, is a state-owned flood control structure located in Tampa, Florida. This structure plays a crucial role in flood risk reduction for the surrounding area, as well as providing benefits for recreation and water supply. With a primary purpose of flood risk reduction, this earth dam stands at a height of 2 feet and has a hydraulic height of 1 foot.
Constructed on Lake Magdalene, Swfwmd Magdelene Control Structure #3 has a maximum storage capacity of 256 acre-feet and a normal storage capacity of 141 acre-feet. The controlled spillway type and outlet gates, which include slide (sluice gate), help regulate water flow and manage flood events effectively. Despite being assessed as in fair condition as of April 2016, the structure is considered to have a significant hazard potential, with a risk assessment rating of very high (1).
Water resource and climate enthusiasts will appreciate the vital role that Swfwmd Magdelene Control Structure #3 plays in managing water levels and mitigating flood risks in the Hillsborough County area. As a state-regulated and state-permitted structure, it is subject to regular inspections and enforcement measures by the Florida Department of Environmental Protection. The structure's location and design make it a crucial component of the flood control infrastructure in the region, ensuring the safety and well-being of local residents and ecosystems.
Dam data reference
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 Swfwmd Magdelene Control Structure #3
Where does the data for Swfwmd Magdelene Control Structure #3 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 Significant 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.
