Muskingum River Lock And Dam No. 9 dam
Muskingum River Lock And Dam No. 9
Muskingum River Lock and Dam No. 9, also known as Philo No. 9 Dam, is a historic timber crib dam located in Duncan Falls, Ohio, on the Muskingum River. Built in 1841 by the U.S. Army Corps of Engineers, this dam serves a primary purpose of recreation, offering visitors a picturesque spot to enjoy water activities and scenic views. The dam has a height of 18.1 feet and a length of 730 feet, with a storage capacity of 3,120 acre-feet and a drainage area of 7,196 square miles.
Despite its historical significance and recreational appeal, Muskingum River Lock and Dam No. 9 is in poor condition and has a significant hazard potential. The dam is state-regulated by the Department of Natural Resources in Ohio, with regular inspections and enforcement measures in place to ensure public safety. The last inspection in October 2018 revealed the dam's deteriorating condition, highlighting the need for maintenance and potential risk management measures to prevent any emergencies or failures.
As a vital structure on the Muskingum River, the conservation and preservation of Muskingum River Lock and Dam No. 9 are crucial for water resource and climate enthusiasts. With its rich history, recreational value, and environmental impact, efforts to improve the dam's condition and ensure its long-term sustainability are essential for the local community and ecosystem. Through collaboration between state agencies, stakeholders, and the public, this historic dam can continue to be a valuable asset for water management and recreation in the region.
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 Muskingum River Lock And Dam No. 9
Where does the data for Muskingum River Lock And Dam No. 9 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 Significant 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.
