Crim Lake Dam dam
Crim Lake Dam
Crim Lake Dam, also known as County Airport Dam, is a privately owned structure located in Shelby, Alabama. Built in 1967, this earth dam serves primarily for recreational purposes and stands at a hydraulic height of 50 feet. The dam has a storage capacity of 440 acre-feet, with a normal storage level of 370 acre-feet. Situated on the Gum Branch river, the dam spans 300 feet in length and is a significant hazard potential structure in the area.
Despite being privately owned and not regulated by the state, Crim Lake Dam has not been rated for its condition assessment. With a significant hazard potential, it is important to note that the dam's emergency action plan has not been prepared or updated, posing potential risks in the case of a dam failure. The dam's lack of inspection frequency and condition assessment raises concerns about its overall safety and the potential impact on the surrounding community in SE Sterrett.
Given its location and potential risks, it is crucial for authorities to address the condition assessment and emergency preparedness of Crim Lake Dam. As a structure with a significant hazard potential, ensuring its safety and compliance with regulatory guidelines is essential to protect both the environment and the local community. Enthusiasts of water resources and climate should closely monitor the developments and management measures taken to mitigate risks associated with this important dam.

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 Crim Lake Dam
Where does the data for Crim 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.
