Sherwood Lake Dam dam
Sherwood Lake Dam
Sherwood Lake Dam, located in Hardy, Arkansas, was completed in 1963 and serves as a recreational reservoir with a primary purpose of providing opportunities for outdoor activities. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Sherwood Lake Dam
Where does the data for Sherwood Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
