Summary
The dam stands at a height of 51 feet and has a hydraulic height of 43 feet, creating a storage capacity of 2023 acre-feet. The dam is situated on the 40-Island Creek river and covers a surface area of 66 acres, making it a popular spot for fishing, boating, and other water-based recreational activities.
Managed by a private owner, Sherwood Lake Dam is regulated by the Arkansas Natural Resources Commission (ANRC) and undergoes regular inspections to ensure its safety and compliance with state regulations. While the dam is rated as having a high hazard potential, its condition assessment is currently listed as "Not Rated." Emergency action plans and risk management measures for the dam are not explicitly documented in the available data, suggesting that further evaluation and preparation may be needed to address potential safety concerns.
Overall, Sherwood Lake Dam provides a valuable recreational resource for the community while also presenting challenges in terms of its hazard potential and emergency preparedness. As water resource and climate enthusiasts, it is important to monitor the condition and management of dams like Sherwood Lake to ensure the safety of both the infrastructure and the surrounding environment. The data available offers insight into the dam's specifications and regulatory oversight, highlighting the need for continued diligence in maintaining and assessing its structural integrity.

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.
