Summary

Built in 1964 by the USDA NRCS, this earth dam stands at a height of 38 feet and has a storage capacity of 4935 acre-feet. It is regulated by the Mississippi Department of Environmental Quality and is designed to mitigate the risk of flooding in the Long Creek watershed.

The dam is classified as having a low hazard potential and a moderate risk assessment rating, making it a crucial piece of infrastructure for water resource management in the region. Although its condition is currently not rated, the structure is regularly inspected, and emergency action plans are in place to ensure the safety of nearby communities in the event of a flood. With its uncontrolled spillway and outlet gates, Black Watershed Structure Y-36-23 Dam plays a vital role in protecting the surrounding area from potential inundation.

Situated in Holmes County, Mississippi, this dam serves as a testament to the importance of proper water resource management and the collaboration between local government agencies and federal organizations like the USDA NRCS. As climate change continues to impact the frequency and severity of extreme weather events, structures like Black Watershed Structure Y-36-23 Dam are essential for safeguarding communities and preserving the natural environment for future generations.

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. 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

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, 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.
