Lock E12 Tribes Hill dam
Lock E12 Tribes Hill
Lock E12 Tribes Hill, located in Montgomery County, New York, is a state-regulated hydroelectric dam on the Mohawk River (Erie Canal). Built in 1910, this dam stands at a height of 11 feet and spans a length of 460 feet, with a storage capacity of 7,199 acre-feet. The dam serves the primary purposes of hydroelectric power generation and navigation, contributing to the region's water resource management and infrastructure development.
Managed by the New York State Department of Environmental Conservation (NYS DEC) and inspected by the Federal Energy Regulatory Commission (FERC), Lock E12 has a low hazard potential and a very high risk rating. Despite its age, the dam's condition assessment is currently listed as not available, highlighting the need for ongoing monitoring and maintenance. With controlled spillways and a designated emergency action plan, Lock E12 is prepared to mitigate potential risks and ensure the safety of surrounding communities in the event of a water-related emergency.
As a vital component of the region's water infrastructure, Lock E12 Tribes Hill serves as a key player in balancing water resource management, energy production, and navigational needs along the Mohawk River. With its historical significance and ongoing regulatory oversight, this hydroelectric dam continues to play a crucial role in supporting sustainable water resource practices and climate resilience efforts in New York State.
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 Lock E12 Tribes Hill
Where does the data for Lock E12 Tribes Hill 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.
