Summary
B. Rowland Pond, located in Isola, Mississippi, is a privately owned dam constructed in 1968 by the USDA NRCS. This earth dam stands at a height of 8 feet and stretches over 10560 feet in length, with a storage capacity of 640 acre-feet. Fed by the TR-Mound Bayou stream, the dam serves a primary purpose other than flood control or water supply, making it a unique feature in the area.
Despite being unregulated by the state and having a low hazard potential, H. B. Rowland Pond poses a moderate risk, with a risk assessment rating of 3. The dam features uncontrolled spillways and outlet gates, indicating limited infrastructure for managing water discharge. While the condition assessment is not rated and there is no recent inspection data available, the risk management measures for the dam remain unspecified, raising questions about the preparedness for potential emergencies and the overall safety of the structure.
For water resource and climate enthusiasts, H. B. Rowland Pond presents an intriguing case study of a privately owned dam with a complex design and operational history. Its location in Humphreys County, Mississippi, offers a glimpse into the region's water management practices and the challenges faced in maintaining aging infrastructure. Further research and monitoring of H. B. Rowland Pond could provide valuable insights into the intersection of water resource management, climate resilience, and dam safety in the area.

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.
