Hollenbeck Lake Dam dam
Hollenbeck Lake Dam
Hollenbeck Lake Dam, located in Parma Heights, Ohio, is a private earth dam constructed in 1953 with a primary purpose of recreation. The dam stands at a height of 23.5 feet and has a storage capacity of 95 acre-feet, providing essential water resources for the surrounding area. However, the dam is assessed to have a high hazard potential and poor condition, raising concerns for the safety of the structure.
Managed by a conservation group and regulated by the Department of Natural Resources in Ohio, the Hollenbeck Lake Dam plays a crucial role in the management of water resources in the region. Despite its recreational benefits, the dam's condition assessment in 2017 highlighted the urgent need for maintenance and potential safety improvements. With a drainage area of 0.65 square miles and a maximum discharge of 566 cubic feet per second, the dam's impact on the local ecosystem and climate resilience underscores the importance of ongoing monitoring and management.
As water resource and climate enthusiasts, understanding the significance of structures like Hollenbeck Lake Dam is vital in safeguarding our environment and communities. With a focus on recreation and water storage, this dam serves as a valuable asset in Cuyahoga County, Ohio. However, its current high hazard potential and poor condition underscore the importance of proactive maintenance and risk management to ensure the safety and sustainability of this essential water resource infrastructure.

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 Hollenbeck Lake Dam
Where does the data for Hollenbeck 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.
