Big Sand Watershed Structure Y-32-17 Dam Reservoir Report
Last Updated: April 1, 2026
The Big Sand Watershed Structure Y-32-17 Dam, also known as Meeks Dam #1, is a vital local government-owned structure in Greenwood City Center, Mississippi.
Summary
Designed by USDA NRCS and completed in 1966, this earth dam serves the primary purpose of flood risk reduction along the Teoc River. Standing at a height of 42 feet with a hydraulic height of 40.5 feet, the dam has a storage capacity of 5692 acre-feet and covers a surface area of 931 acres, impacting a drainage area of 13.65 square miles.
Despite its crucial role in mitigating flood risks, the dam's condition assessment is marked as "poor" with a high hazard potential. The last inspection in September 2020 revealed maintenance concerns, indicating a need for further attention and potential risk management measures. The dam's uncontrolled spillway and outlet gates pose additional challenges, highlighting the importance of regular inspections and maintenance to ensure the structure's integrity and the safety of downstream communities. Water resource and climate enthusiasts will find the Big Sand Watershed Structure Y-32-17 Dam a compelling case study in the ongoing efforts to manage and maintain critical infrastructure in the face of changing environmental conditions.

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.
