Dam At Lock E 27 dam
Dam At Lock E 27
Located in Lyons, New York, the Dam At Lock E 27 stands as a testament to engineering excellence since its completion in 1910. This concrete structure serves multiple purposes including flood risk reduction, hydroelectric power generation, and navigation along the ERIE CANAL CLYDE RIVER. With a height of 23 feet and a length of 169 feet, the dam has a storage capacity of 1250 acre-feet and covers a surface area of 82 acres, benefiting the surrounding area by protecting against flooding and supporting water-based transportation.
Managed by the New York State Department of Environmental Conservation, the Dam At Lock E 27 poses a low hazard potential with a moderate risk assessment rating. Despite its age, the dam has not been rated for condition assessment, and the last inspection in 2013 confirmed its structural integrity. With an uncontrolled spillway width of 85 feet, the dam remains a vital piece of infrastructure in the region. It is a reminder of the importance of water resource management in mitigating the impacts of climate change and ensuring sustainable development in the area.
As a state-regulated structure, the Dam At Lock E 27 plays a crucial role in the region's water resource management efforts. It not only reduces flood risks but also supports hydroelectric power generation and facilitates navigation. With a rich history dating back over a century, this concrete dam stands as a symbol of resilience and innovation in the face of changing climate patterns. As enthusiasts of water resources and climate, we recognize the significance of this structure in promoting sustainable development and protecting communities from the adverse impacts of extreme weather events.

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 Dam At Lock E 27
Where does the data for Dam At Lock E 27 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.
