About this dam

Craig Field Lake Dam

Craig Field Lake Dam in Dallas County, Alabama, is a significant earth dam that was completed in 1950 for the primary purpose of recreation. With a hydraulic height of 15 feet and a structural height of 20 feet, this dam spans a length of 790 feet and has a storage capacity of 168 acre-feet. Situated east of Blackwell Bend and utilizing TR-Fourmile Creek as the river or stream source, Craig Field Lake Dam is owned and operated by the local government.

This dam, located in the Mobile District of Alabama, has a maximum discharge rate of 1075 cubic feet per second and is considered to have a significant hazard potential. While the condition assessment is currently not rated, the dam has not undergone recent inspections or been equipped with an Emergency Action Plan (EAP). Despite not being regulated by the state, Craig Field Lake Dam serves as a crucial recreational resource for the surrounding community, offering opportunities for fishing, boating, and other water-based activities.

For water resource and climate enthusiasts, Craig Field Lake Dam presents an intriguing case study in dam infrastructure management. With its historical construction date and notable storage capacity, this earth dam raises questions about maintenance practices, risk assessment, and emergency preparedness. As a local government-owned structure, the dam's condition assessment and hazard potential underscore the importance of ongoing monitoring and evaluation to ensure the safety and sustainability of this vital water resource in Dallas County, Alabama.

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 Craig Field Lake Dam

Where does the data for Craig Field Lake Dam 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.
