Smyer Lake Dam Number Two dam
Smyer Lake Dam Number Two
Smyer Lake Dam Number Two, also known as Great Pine Dam, is a private rockfill dam located in Shelby County, Alabama. Built in 1953 on Shoal Creek, this dam serves primarily for recreational purposes, offering a storage capacity of 820 acre-feet with a normal storage volume of 240 acre-feet. With a hydraulic height of 18 feet and a structural height of 18 feet, this dam stands at a length of 180 feet and has a high hazard potential.
Situated in the city of Dunavant, this dam is under the jurisdiction of the Mobile District of the US Army Corps of Engineers and falls within Congressional District 06 of Alabama, represented by Gary J. Palmer. While the dam has not been rated for its condition, it is regularly inspected, although the last inspection date is not available. Despite its high hazard potential, there are no Emergency Action Plans (EAP) prepared for this dam, raising concerns about its safety and risk management measures in case of emergencies.
Water resource and climate enthusiasts would be intrigued by the data on Smyer Lake Dam Number Two, a significant structure on Shoal Creek in Alabama. As a private dam primarily used for recreation, this dam's design, construction, and management offer valuable insights into the intersection of human infrastructure and natural water systems. The lack of certain regulatory measures and emergency preparedness highlights the importance of ongoing monitoring and assessment for ensuring the safety and sustainability of water resources in the region.

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 Smyer Lake Dam Number Two
Where does the data for Smyer Lake Dam Number Two 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 High 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.
