Noralyn N-9 Dam
Noralyn N-9
Noralyn N-9 is a private earth dam located in Polk, Florida, specifically in Fort Meade. Completed in 1961, this dam serves the primary purpose of debris control and stands at a height of 40 feet with a structural height of 35 feet. With a storage capacity of 25,133 acre-feet and a surface area of 1,214 acres, Noralyn N-9 plays a vital role in managing water resources in the area.
Situated on an unnamed pond, Noralyn N-9 is regulated by the state of Florida, with permitting, inspection, and enforcement procedures in place to ensure its safe operation. Despite being classified as having a low hazard potential and not yet rated for condition assessment, this dam serves as a crucial infrastructure for water management in the region. Its location and design make it a key player in maintaining water quality and flow in the surrounding area.
With a history dating back to the early 1960s, Noralyn N-9 continues to provide valuable debris control and water storage capabilities for the community. As a non-federal structure, it represents a partnership between private ownership and state regulatory agencies to maintain safe and efficient water resource management. As water resource and climate enthusiasts, understanding the significance of structures like Noralyn N-9 is essential in appreciating the intricate network of infrastructure that supports our water ecosystems.

About Noralyn N-9
Where does the data for Noralyn N-9 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.
