Hap Cremean Lagoon #1 dam
Hap Cremean Lagoon #1
Hap Cremean Lagoon #1, located in Franklin, Ohio, is a significant earth dam completed in 2011 for the primary purpose of tailings storage. Managed by the local government and regulated by the Department of Natural Resources, this dam stands at a height of 14 feet, with a storage capacity of 232.9 acre-feet. The dam covers a surface area of 17 acres and serves the drainage area of Big Walnut Creek offstream.
Despite its significant hazard potential, Hap Cremean Lagoon #1 has been assessed to be in satisfactory condition as of December 2020. Regular inspections are conducted every 5 years to ensure its structural integrity and safety. The dam has a spillway width of 0 feet and does not have any outlet gates or associated structures. With a solid track record of compliance with state regulations, this lagoon plays a crucial role in water resource management in the region.
Water resource and climate enthusiasts will find Hap Cremean Lagoon #1 to be a fascinating case study in dam engineering and management. Its location, design, and purpose offer valuable insights into the intersection of human infrastructure with natural water systems. As efforts to address climate change and ensure water security continue to be a global priority, understanding the role of dams like Hap Cremean Lagoon #1 is essential for sustainable water resource management.

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 Hap Cremean Lagoon #1
Where does the data for Hap Cremean Lagoon #1 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.
