Pleasant Valley Lake Dam dam
Pleasant Valley Lake Dam
Pleasant Valley Lake Dam, located in Tibbetts Corners, Ohio, is a privately owned structure along Squaw Creek with a primary purpose of recreation. Built in 1925, this earth-type dam stands at a height of 20.3 feet and has a storage capacity of 139.7 acre-feet, offering a surface area of 11.3 acres for recreational activities. However, despite its scenic setting and historical significance, the dam is currently rated as having a high hazard potential and poor condition assessment.
Managed by the Department of Natural Resources in Ohio, Pleasant Valley Lake Dam has a state-regulated status with provisions for permitting, inspection, and enforcement. The last inspection in May 2016 highlighted the need for improvements and a potential emergency action plan considering the dam's high hazard potential. With a drainage area of 3.65 square miles and a maximum discharge capacity of 1005 cubic feet per second, any failure or breach of this dam could have significant consequences for the surrounding Trumbull County community.
While Pleasant Valley Lake Dam serves as a popular recreation spot, its structural integrity and maintenance are critical concerns for water resource and climate enthusiasts. As efforts are made to address its poor condition assessment and high hazard potential, stakeholders must prioritize safety measures and risk management strategies to ensure the long-term sustainability and resilience of this historic dam in Ohio's water infrastructure landscape.

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 Pleasant Valley Lake Dam
Where does the data for Pleasant Valley Lake 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.
