Warner Dam dam
Warner Dam
Warner Dam, also known as Chautauqua Lake Outlet Dam, is a concrete structure located in Jamestown, New York, along the Chadakoin River. Completed in 1979, this dam serves primarily for recreational purposes, offering a surface area of 13421 acres for water activities. With a height of 12 feet and a length of 96 feet, Warner Dam has a storage capacity of 117,105 acre-feet, providing essential water resources for the region.
Managed by the New York State Department of Environmental Conservation, Warner Dam is regulated and inspected regularly to ensure its structural integrity and compliance with safety standards. The dam has a significant hazard potential, and a moderate risk assessment rating indicates the need for ongoing risk management measures. Despite not being rated for its condition, Warner Dam remains a crucial infrastructure for water resource management and climate adaptation in Chautauqua County.
As a key feature in the Buffalo District, Warner Dam plays a vital role in managing water flow and protecting downstream areas from flooding. With its uncontrolled spillway type and maximum discharge capacity of 6,629 cubic feet per second, the dam is essential for maintaining water levels and preventing potential disasters. As climate change continues to impact the region, Warner Dam stands as a critical asset for water resource enthusiasts and climate advocates alike, highlighting the importance of sustainable infrastructure in a changing environment.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Warner Dam
Where does the data for Warner 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.
