Summary
4, also known as Beverly No. 4, is a historic timber crib dam completed in 1841 by the U.S. Army Corps of Engineers. This state-owned structure serves primarily for recreation purposes, offering visitors a tranquil spot for boating, fishing, and enjoying the scenic beauty of the surrounding area. With a dam height of 17 feet and a storage capacity of 3,345 acre-feet, this dam plays a significant role in regulating water flow along the river.
Despite its historical significance and recreational value, Muskingum River Lock and Dam No. 4 is currently assessed as being in poor condition, with a significant hazard potential. The last inspection in October 2018 revealed this assessment, prompting a closer look at its structural integrity and safety measures. The Department of Natural Resources in Ohio oversees the regulatory aspects of the dam, ensuring that inspections, permitting, and enforcement are carried out to maintain public safety and the dam's functionality. As a vital piece of Ohio's water resource infrastructure, efforts to address the dam's condition and mitigate risks are crucial for its continued use and preservation in the face of changing climate patterns.

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.
