Dredged Spoil Retention Area C Dam
Dredged Spoil Retention Area C
Dredged Spoil Retention Area C is a private water resource structure located in Hillsborough, Florida, along the Alafia River. Built in 1978, this earth dam stands at a height of 36 feet and stretches over 6,100 feet in length, providing a storage capacity of 155 acre-feet. Despite its low hazard potential, the dam has not been rated for its current condition, and there is no information available on its inspection frequency or emergency action plan.
The primary purpose of Dredged Spoil Retention Area C is categorized as "Other," indicating its role in managing dredged spoil material and potentially serving additional functions beyond standard water resource management. The structure falls under state regulation, with permitting, inspection, and enforcement responsibilities clearly outlined. Its location in a private ownership setting highlights the importance of private entities in managing water resources and infrastructure in the region.
With a limited surface area of 4 acres and no designated drainage area, Dredged Spoil Retention Area C remains a unique water resource feature along the Alafia River. While its risk assessment and management measures are not specified in the available data, the structure's presence adds to the diverse landscape of water management infrastructure in Florida. Enthusiasts interested in water resource management and climate resilience in the region may find value in further exploring the role and significance of Dredged Spoil Retention Area C in the local water ecosystem.

About Dredged Spoil Retention Area C
Where does the data for Dredged Spoil Retention Area C 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 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.
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.
