About this dam

Marshall Patterson

Marshall Patterson is a privately owned recreational dam located in Escambia, Alabama, within the Mobile District of the US Army Corps of Engineers. With a significant hazard potential and a condition assessment that is currently not rated, this dam presents an intriguing case for water resource and climate enthusiasts. While its primary purpose is for recreation, the dam's specifications such as height, volume, and storage capacity are not available, adding to the mystery and allure surrounding this structure.

Despite being privately owned, Marshall Patterson falls under the jurisdiction of the state of Alabama, with no state regulatory agency overseeing its operations. The dam's emergency action plan status, risk assessment, and management measures are also unknown, leaving room for speculation and further investigation into its safety and environmental impact. The presence of associated structures and the absence of detailed information on outlet gates and inspection frequency add layers of complexity to the dam's story, making it a fascinating subject for those interested in water management and climate resilience.

As water resources become increasingly critical in the face of climate change, Marshall Patterson stands as a reminder of the interconnectedness between human infrastructure and the natural environment. Its location in Escambia County, Alabama, highlights the importance of understanding the risks and potential consequences associated with dams, especially in areas prone to extreme weather events. Delving deeper into the history and management of Marshall Patterson can provide valuable insights into the challenges and opportunities of balancing recreation, safety, and environmental protection in the realm of water resource management.

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.

FAQ

About Marshall Patterson

Where does the data for Marshall Patterson 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 Significant 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.
