Briarwood Sportsman's Club No. 11 Dam dam
Briarwood Sportsman's Club No. 11 Dam
Briarwood Sportsman's Club No. 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.
Dam data reference
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 Briarwood Sportsman's Club No. 11 Dam
Where does the data for Briarwood Sportsman's Club No. 11 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.
