Howell Lake Number 2 Dam dam
Howell Lake Number 2 Dam
Howell Lake Number 2 Dam, located in Oktibbeha, Mississippi, is a private-owned structure regulated by the Mississippi Department of Environmental Quality. This earth dam with a buttress core stands at a height of 10 feet and has a storage capacity of 56 acre-feet, primarily serving recreational purposes. The dam features an uncontrolled spillway and is currently classified as having an undetermined hazard potential and a moderate risk assessment rating.
While specific details such as the year of completion, dam length, and surface area are not provided, the dam's overall condition is marked as "Not Rated," indicating a need for further assessment. Despite this, the dam has not been identified as a high-risk structure, with no Emergency Action Plan (EAP) in place at present. The surrounding area's inundation maps and risk management measures are also not yet prepared or documented, suggesting a potential area for improvement in terms of emergency preparedness and response.
Overall, Howell Lake Number 2 Dam presents an interesting case study for water resource and climate enthusiasts, highlighting the importance of regulatory oversight, risk assessment, and emergency planning for private-owned dams. Further evaluation and monitoring of the dam's condition, as well as the implementation of appropriate safety measures, could help ensure the continued safety and functionality of this recreational structure in Mississippi.

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 Howell Lake Number 2 Dam
Where does the data for Howell Lake Number 2 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 Undetermined 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.
