Summary
11 Dam, located in Zanesfield, Ohio, is a privately owned earth dam completed in 1976 for recreational purposes. The dam stands at a height of 49.9 feet and has a storage capacity of 303 acre-feet, with a surface area of 17.1 acres and a drainage area of 0.84 square miles. The dam is situated on a tributary to the Mad River and is regulated by the Ohio Department of Natural Resources.
Despite its recreational focus, the dam has been classified as having a high hazard potential and a poor condition assessment as of the last inspection in November 2019. With an inspection frequency of 5 years, the dam's emergency action plan status, risk assessment, and inundation maps preparation are not currently up to date. The overall risk management measures for the dam are also unspecified, raising concerns for potential safety issues in the event of a dam failure.
Water resource and climate enthusiasts may find Briarwood Sportsman's Club No. 11 Dam an intriguing case study due to its recreational purpose, high hazard potential, and the need for updated safety measures. The dam's location, design, and condition provide a unique opportunity for further research and analysis in understanding the intersection of water management, infrastructure safety, and regulatory oversight in the context of climate change impacts on dam safety.

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.
