Hosey (Maumee River) Dam (In-Channel) dam
Hosey (Maumee River) Dam (In-Channel)
The Hosey (Maumee River) Dam in Indiana serves as a crucial structure for the management of fish and wildlife ponds, with a primary purpose of supporting aquatic ecosystems. Completed in 1925, this concrete dam stands at a height of 10 feet and stretches 475 feet in length, providing storage of 874 acre-feet of water. Situated on the Maumee River in Allen County, Indiana, the dam plays a vital role in regulating water flow and supporting the habitat of various species.
Despite its age, the Hosey Dam is considered to have a low hazard potential and is rated in fair condition as of the last assessment in 2001. With a maximum discharge capacity of 2150 cubic feet per second, the dam operates with Tainter radial gates for water control. The risk assessment for the dam indicates a high risk level (2), prompting the need for continued monitoring and potential risk management measures to ensure the safety and functionality of the structure.
As a publicly owned utility structure, the Hosey (Maumee River) Dam is subject to state regulation, permitting, inspection, and enforcement by the Indiana Department of Natural Resources. With its location in the Maumee River watershed and its role in supporting fish and wildlife habitats, this dam stands as a vital component of water resource management in the region, highlighting the intersection of infrastructure, ecology, and climate resilience.
Dam data reference
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 Hosey (Maumee River) Dam (In-Channel)
Where does the data for Hosey (Maumee River) Dam (In-Channel) 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 Low 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.
