Summary

Completed in 1969, this dam stands at a height of 40 feet and has a storage capacity of 10,725 acre-feet. Situated on an unnamed pond in Polk County, Noralyn N-13 plays a crucial role in managing water resources in the area.

Despite its low hazard potential, Noralyn N-13 is regulated by the state of Florida and undergoes regular inspections, ensuring its structural integrity and safety. With a hydraulic height of 40 feet and a length of 4,950 feet, this dam serves as a vital infrastructure for water management and flood control in the region. As climate change continues to impact water resources, structures like Noralyn N-13 play a crucial role in safeguarding communities and ecosystems from potential risks.

As water resource and climate enthusiasts continue to monitor and assess the impact of climate change on our water systems, Noralyn N-13 stands as a testament to the importance of sustainable water management practices. With its strategic location, efficient design, and regulatory oversight, this earth dam serves as a key asset in ensuring the resilience of water resources in Polk County, Florida, and beyond.

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.
