Hendrickson Dam dam
Hendrickson Dam
Hendrickson Dam, also known as Shell Creek Dam, is a local government-owned structure located in Charlotte, Florida. Completed in 1965, this dam serves primarily as a water supply source, with a storage capacity of 10,500 acre-feet and a normal storage level of 2,450 acre-feet. The dam stands at a height of 17 feet and spans a length of 1,000 feet along Shell Creek, a river in the area.
Despite its low hazard potential, Hendrickson Dam is regulated and inspected by the state of Florida, ensuring its compliance with safety standards and operational effectiveness. The dam's condition is currently rated as "Not Rated," indicating a need for further assessment. While it has not undergone recent modifications or inspections, the dam remains a vital infrastructure for water resource management in the region, with a maximum discharge capacity of 30,836 cubic feet per second.
Enthusiasts of water resources and climate in the area can appreciate the significance of Hendrickson Dam in providing a reliable water supply for the community. Its strategic location and design contribute to the sustainable management of water resources in Charlotte, Florida, reflecting the importance of infrastructure in addressing the challenges of climate variability and water scarcity. As efforts continue to monitor and maintain the dam's safety, it stands as a testament to the critical role of dams in supporting water security and resilience in the face of changing environmental conditions.

About Hendrickson Dam
Where does the data for Hendrickson Dam 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.
