Oc4 dam
Oc4
Located in Okaloosa, Florida, the Oc4 dam is a private structure primarily used for recreational purposes. Standing at 14 feet tall and spanning 526 feet in length, it holds a storage capacity of 336 acre-feet of water in an unnamed pond. Although its hazard potential is currently labeled as undetermined and its condition assessment is marked as "Not Rated," the dam is regulated by the state of Florida, with permitting, inspection, and enforcement all in place to ensure its safety and compliance.
Operated by private owners, Oc4 serves as a popular spot for outdoor activities in Crestview, offering a surface area of 23 acres for recreational use. Despite lacking detailed information on its construction date and modifications over the years, the dam remains a focal point for water resource and climate enthusiasts interested in exploring the diverse landscapes of Florida. With its surroundings providing a serene backdrop for nature lovers, Oc4 invites visitors to enjoy its tranquil setting and engage in various recreational pursuits.
While the dam's emergency action plan status, risk assessment, and management measures are not specified in the available data, the structure's presence adds to the unique water infrastructure of the region. As water resource enthusiasts continue to monitor the environmental impact of dams like Oc4, their role in shaping the local ecosystem and providing opportunities for outdoor recreation remains a subject of interest and exploration in the realm of water management and climate resilience.

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.

About Oc4
Where does the data for Oc4 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 Undetermined 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 above 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.
