Rawson Wwt Lagoon dam
Rawson Wwt Lagoon
Rawson Wwt Lagoon, located in Hancock County, Ohio, is a significant earth dam completed in 2003 with a height of 15 feet and a length of 5100 feet. The lagoon has a storage capacity of 82 acre-feet and covers a surface area of 12.4 acres, serving as a crucial water resource for the area. It is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections to ensure its structural integrity and safety.
The dam on Ottawa Creek is owned by the local government and has a primary purpose of "Other," with a satisfactory condition assessment as of the last inspection in September 2019. Despite its significant hazard potential, the lagoon is well-maintained and meets regulatory guidelines, providing essential water storage and drainage functions for the region. The dam's emergency action plan was last reviewed in July 2020, demonstrating a commitment to preparedness and risk management.
Rawson Wwt Lagoon is a vital infrastructure project designed by Feller, Finch & Associates Inc, serving the community with reliable water storage and discharge capabilities. With a maximum discharge of 11.2 cubic feet per second, the dam plays a crucial role in managing water levels and mitigating flood risks in the area. Its location on Ottawa Creek highlights the importance of sustainable water resource management in the face of changing climate patterns and increasing water demand.

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 Rawson Wwt Lagoon
Where does the data for Rawson Wwt Lagoon 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.
