Summary
B. Evans Lake is a private water resource located in Humphreys, Mississippi, just 8 miles away from Belzoni. Managed by the USDA NRCS, this earth dam was completed in 1968 and serves multiple purposes, with a primary focus on agricultural and environmental needs. The lake has a capacity of 320 acre-feet and a low hazard potential rating, making it a vital resource for the local community.
With a spillway width of 1 foot and uncontrolled outlet gates, A. B. Evans Lake is designed to handle a maximum discharge of 2 cubic feet per second. The dam structure stands at 8 feet tall and spans over 10,000 feet in length, providing essential water storage for the surrounding area. While the condition assessment is currently marked as "Not Rated," the risk assessment categorizes the lake as having a moderate risk level, signaling the need for ongoing monitoring and management measures to ensure its safety and functionality in the face of climate challenges.
Despite not being under state jurisdiction or regulation, A. B. Evans Lake plays a crucial role in water resource management within the region. As part of the Vicksburg District and the broader network of natural resource conservation efforts, this lake stands as a testament to the collaborative efforts needed to safeguard water supplies in the face of changing climates. With its strategic location along the TR- Yazoo River and the endorsement of the Natural Resources Conservation Service, A. B. Evans Lake serves as a valuable asset for both agricultural and environmental sustainability 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.
