Summary
It serves a primary purpose of recreation and is classified as an earth dam with buttress core types. With a height of 16 feet and a storage capacity of 108 acre-feet, the dam's hazard potential is currently undetermined, and its condition is not rated.
Located in Montgomery County, Mississippi, this dam poses a moderate risk according to the data provided. While it has not been assessed for emergency preparedness or undergone recent inspections, it is important to note its presence for water resource and climate enthusiasts in the area. The dam's uncontrolled spillway and lack of outlet gates indicate potential vulnerabilities that may need to be addressed in the future for safe operation and risk management.
Despite its relatively small size and limited information available, J H Collins Lake Dam is a noteworthy structure for those interested in water resource management and the impact of dams on local ecosystems. Its recreational purpose and moderate risk level highlight the importance of proper maintenance and monitoring to ensure the safety and sustainability of this water infrastructure in Mississippi.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
