About this dam

Troy Low Head Dam

The Troy Low Head Dam, located in Tipp City, Ohio, along the Great Miami River, is a gravity dam primarily used for recreation purposes. Owned by the local government, this dam stands at a height of 9.38 feet and has a storage capacity of 150 acre-feet. With a surface area of 45 acres and a drainage area of 926 square miles, the dam provides both recreational opportunities and important water resource management functions in the region.

Managed by the Department of Natural Resources in Ohio, the Troy Low Head Dam is regulated and inspected regularly to ensure safety and compliance with state regulations. Despite its significant hazard potential, the dam has been assessed as satisfactory in condition, with the last inspection conducted in September 2019. With a history of providing water storage for the surrounding area, the dam serves as a crucial infrastructure for managing water resources and supporting recreational activities along the Great Miami River.

Climate and water resource enthusiasts will find the Troy Low Head Dam an intriguing structure, contributing to both local recreation and water management efforts. With its location in Miami County, Ohio, this dam plays a vital role in maintaining water levels, supporting wildlife habitats, and offering recreational opportunities for residents and visitors alike. As a gravity dam with a history of fulfilling multiple purposes, the Troy Low Head Dam exemplifies the intersection of infrastructure, water resource management, and environmental stewardship in the region.

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 Troy Low Head Dam

Where does the data for Troy Low Head 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.
