Brogden Bridge dam
Brogden Bridge
Brogden Bridge, located in Hernando, Florida, serves as a critical infrastructure for flood risk reduction along Lake Tsala Apopka. This state-regulated structure, owned by the state of Florida, was completed in 1972 and has a dam height of 7.25 feet, with a hydraulic height of 6.5 feet and a structural height of 17 feet. With a maximum storage capacity of 2970 acre-feet and a normal storage capacity of 29700 acre-feet, the dam plays a crucial role in managing water levels and mitigating flood risks in the area.
The controlled spillway of Brogden Bridge, with a width of 82 feet, ensures efficient water discharge during high flow events, while the structure's low hazard potential and very high risk assessment highlight the importance of ongoing monitoring and maintenance. Despite being classified as "Not Rated" in terms of condition assessment, the dam remains a key asset in the region's water resource management strategy. With the State of Florida taking on the responsibility of permitting, inspecting, and enforcing regulations related to the dam, stakeholders can be assured of the structure's continued functionality in safeguarding the community against flood hazards.
In the heart of Citrus County, Florida, Brogden Bridge stands as a testament to the collaboration between state agencies and local communities in addressing climate-related challenges. As water resource and climate enthusiasts continue to advocate for sustainable water management practices, the role of structures like Brogden Bridge in ensuring the resilience of ecosystems and communities against the impacts of a changing climate remains paramount. With a rich history dating back to its completion in 1972, Brogden Bridge symbolizes the ongoing efforts to balance flood risk reduction with environmental stewardship in a rapidly evolving climate landscape.
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 Brogden Bridge
Where does the data for Brogden Bridge 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.
