J M Granger dam
J M Granger
J M Granger is a private fish and wildlife pond located in Parker Creek Subdivision in Coosa, Alabama. Built in 1968 by the USDA NRCS, this Earth dam stands at 15 feet tall and stretches for 300 feet. With a storage capacity of 66 acre-feet and a drainage area of 0.13 square miles, this dam serves primarily for fish and wildlife purposes, as well as for recreation. Despite its low hazard potential and moderate risk assessment, it has not been inspected since March 1980 and is currently rated as "Not Rated" in terms of condition assessment.
Situated in Congressional District 06 of Alabama, J M Granger is owned by a private entity and falls under the jurisdiction of the state without any regulatory agency involvement. Although classified as an uncontrolled spillway type with a spillway width of 36 feet, this dam has not undergone any modifications or inspections in recent years. With its location in a picturesque setting in Coosa County, this dam provides a serene environment for wildlife and recreational activities, yet its lack of recent assessments raises concerns about its long-term safety and maintenance.
For water resource and climate enthusiasts, J M Granger offers a fascinating case study of a privately owned dam with a specific focus on fish and wildlife conservation. With its historical significance dating back to the late 1960s, this Earth dam continues to provide essential ecosystem services in the form of habitat preservation and recreational opportunities. However, the lack of recent inspections and condition assessments highlights the importance of regular monitoring and maintenance to ensure its continued functionality and safety for both the environment and surrounding community.

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 J M Granger
Where does the data for J M Granger 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.
