Summary
Clairsville Reservoir No. 2 Dam, also known as Provident Reservoir, was completed in 1920 and is owned by the local government. The dam, with a height of 31 feet and a length of 260 feet, serves primarily as a water supply structure for the surrounding area. Situated on the Jug Run river, the dam has a storage capacity of 86.7 acre-feet and a normal storage of 52.2 acre-feet, covering a surface area of 4.9 acres and draining an area of 1.13 square miles.
Managed by the Department of Natural Resources in Ohio, the St. Clairsville Reservoir No. 2 Dam has a high hazard potential but was assessed as being in satisfactory condition during the last inspection in November 2017. With a regular inspection frequency of 5 years, the dam meets state regulations and permits, ensuring its safety and functionality. While no spillway type or outlet gates are specified, the dam serves as a crucial infrastructure for water resource management in the region, playing a vital role in ensuring water supply for the local community.
Water resource and climate enthusiasts will appreciate the historical significance and engineering details of the St. Clairsville Reservoir No. 2 Dam. Its design by the Clarkson Coal Company, modified by Herbert and Herbert, reflects early 20th-century engineering practices in dam construction. The dam's location on the Jug Run river adds to its ecological value, providing habitat for aquatic species and contributing to the local hydrological cycle. As a key component of the water supply infrastructure in Belmont County, Ohio, the dam underscores the importance of sustainable water management practices in the face of changing climate conditions.

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.
