Gp2 dam
Gp2
Gp2 is a privately owned dam located in Gulf, Florida, specifically in Port St. Joe. This Earth-type dam stands at a height of 21 feet and stretches 7240 feet in length, with a storage capacity of 2174 acre-feet. The primary purpose of Gp2 is for recreation, providing a surface area of 68 acres for various water activities. Despite being privately owned, the dam is regulated by the state of Florida and undergoes regular inspections to ensure its safety and compliance with state regulations.
Situated on an unnamed pond in S36, T7S, R11W, Gp2 remains an essential structure for recreational use in the area. The hazard potential of the dam is currently undetermined, with its condition not rated as of yet. Although not owned or funded by federal agencies, Gp2 serves as a valuable resource for water enthusiasts in the region. As climate change continues to impact water resources, it is crucial to monitor and maintain dams like Gp2 to ensure their safety and longevity for future generations to enjoy.
While the exact year of completion and last inspection date for Gp2 are unknown, the dam remains a key feature in the landscape of Port St. Joe. With its structural integrity and storage capacity, Gp2 provides a recreational outlet for residents and visitors alike. As water resource and climate enthusiasts, it is essential to appreciate and support the maintenance of structures like Gp2 to preserve and protect our natural environment for years to come.

About Gp2
Where does the data for Gp2 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 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.
