About this dam

Hidden Valley Acres Dam

Hidden Valley Acres Dam, located in Holmes County, Ohio, is a privately owned structure regulated by the Department of Natural Resources and used primarily for recreational purposes. Completed in 1958, this earth dam stands at a height of 30.4 feet and has a storage capacity of 94.2 acre-feet. However, recent inspections have deemed the dam to be in poor condition with a significant hazard potential, indicating a need for maintenance and potential risk management measures.

Situated on the Upper Sand Run river, this dam not only provides recreational opportunities for the local community but also serves as a critical infrastructure for water resource management in the area. With a drainage area of 0.87 square miles and a maximum discharge rate of 66 cubic feet per second, the dam plays a crucial role in controlling water flow and ensuring the safety of downstream areas. Despite its current condition assessment, efforts are likely needed to improve the structural integrity and safety of Hidden Valley Acres Dam.

For water resource and climate enthusiasts, Hidden Valley Acres Dam presents an intriguing case study on the importance of regular inspection, maintenance, and risk management for dams. With its significant hazard potential and poor condition assessment, this structure serves as a reminder of the need for proactive measures to ensure the safety and sustainability of water infrastructure. As discussions around climate change and extreme weather events continue to grow, the role of dams like Hidden Valley Acres in mitigating risks and protecting communities becomes increasingly vital.

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.

FAQ

About Hidden Valley Acres Dam

Where does the data for Hidden Valley Acres 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 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.
