Sa 11 S.R. Dam
Sa 11 S.R.
Sa 11 S.R. is a privately owned dam located in Hamilton, Florida, along the Suwannee River. Constructed in 1988 by ARDAMAN & ASSOCIATES, this Earth-type dam stands at a height of 23 feet with a hydraulic height of 18 feet and a structural height of 28 feet. With a storage capacity of 16,000 acre-feet and a normal storage of 13,500 acre-feet, this dam serves primarily for recreational purposes, including tailings management.
The dam, with a length of 28,000 feet and a surface area of 736 acres, has a controlled spillway type with a width of 64 feet. Despite its low hazard potential, Sa 11 S.R. has a very high risk assessment rating of 1, indicating the need for careful risk management measures. The dam has not been rated for its condition, and the last inspection conducted was in September 2005. It is important for water resource and climate enthusiasts to monitor the maintenance and safety of Sa 11 S.R. to ensure the protection of the surrounding environment and communities.
In the event of an emergency, the dam's emergency action plan status, inundation maps, and risk management guidelines are not readily available. With its location in a high-risk area, the potential consequences of a dam failure could be severe. Therefore, it is crucial for relevant authorities to update and adhere to proper emergency protocols to mitigate any potential risks associated with Sa 11 S.R.

About Sa 11 S.R.
Where does the data for Sa 11 S.R. 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.

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.
