Summary

Completed in 1978, this concrete dam stands at a height of 2.5 feet, with a hydraulic height of 10.8 feet and a structural height of 18.5 feet. The primary purpose of Schg is flood risk reduction, helping to mitigate potential damage in the event of heavy rainfall or flooding.

With a storage capacity of 950 acre-feet and a maximum discharge of 2475 cubic feet per second, Schg plays a crucial role in managing water flow along Rocky Creek. The dam covers a surface area of 75 acres and serves a drainage area of 43.7 square miles. Despite its significant hazard potential, the condition of Schg has not been rated, with the last inspection taking place in September 1999. The risk assessment for Schg categorizes it as having a very high risk level, emphasizing the importance of effective risk management measures to ensure the safety and functionality of the structure.

As a key component of the water management infrastructure in Florida, Schg highlights the ongoing efforts to balance flood risk reduction with efficient water resource management. Its location in a high-risk area underscores the importance of regular inspections and maintenance to uphold its structural integrity and safeguard surrounding communities. Climate and water resource enthusiasts can appreciate the critical role that Schg plays in protecting against flooding and preserving the delicate balance of water resources in the region.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
