H G Quinnelly dam
H G Quinnelly
H G Quinnelly is a private recreational dam located in Mobile, Alabama, along the TR-CHICKASAW CREEK. Built in 1950, this earth dam stands at a hydraulic height of 18 feet and a structural height of 23 feet, with a length of 1200 feet. It has a normal storage capacity of 158 acre-feet and a maximum discharge of 2000 cubic feet per second. Despite its age, the dam is classified as having a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
This dam, owned privately, serves primarily for recreation purposes and is not regulated by the state of Alabama. It has a maximum storage capacity of 200 acre-feet and has not undergone any major modifications since its completion. The surrounding area of Gulfcrest benefits from the presence of H G Quinnelly for recreational activities such as fishing and boating. While the dam has not been rated for its emergency action plan or risk assessment, its low hazard potential indicates a relatively low level of risk for potential incidents.
In the congressional district of Alabama, this dam falls under the jurisdiction of Representative Bradley Byrne (R) and the Mobile District of the US Army Corps of Engineers. Despite its relatively small size and capacity, H G Quinnelly plays a significant role in providing recreational opportunities in the region while maintaining a low risk profile. Water resource and climate enthusiasts in the area can appreciate the importance of this dam in balancing human recreation with the preservation of natural resources.

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 H G Quinnelly
Where does the data for H G Quinnelly 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 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.
