Muskingum River Lock And Dam No. 11 dam
Muskingum River Lock And Dam No. 11
Muskingum River Lock and Dam No. 11, also known as Ellis No. 11, is a historic timber crib dam located in Muskingum, Ohio. Built in 1841 by the U.S. Army Corps of Engineers, this dam has a height of 15.3 feet and a length of 340 feet, creating a storage capacity of 1461 acre-feet. Situated on the Muskingum River, this dam serves primarily for recreational purposes, offering opportunities for boating, fishing, and other water-related activities in the area.
The dam is owned and regulated by the state of Ohio, with the Department of Natural Resources overseeing its operation, inspection, and enforcement. Despite being labeled as having "Significant" hazard potential, the dam is currently assessed to be in "Fair" condition as of the last inspection in October 2018. With a drainage area of 6036 square miles and a maximum discharge capacity of 11594 cubic feet per second, this dam plays a crucial role in managing water resources and mitigating flood risks in the region.
As a key structure on the Muskingum River, Lock and Dam No. 11 not only provides recreational benefits but also contributes to water resource management and flood control efforts in the area. With its historical significance and continued importance in the region, this dam serves as a valuable asset for both water resource and climate enthusiasts interested in the intersection of infrastructure, environment, and recreation along the Muskingum River.
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. 11
Where does the data for Muskingum River Lock And Dam No. 11 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.
