Patterson Brixius Grey Watershed 1 Dam dam
Patterson Brixius Grey Watershed 1 Dam
The Patterson Brixius Grey Watershed 1 Dam, also known as the Toronto Reservoir, is a vital structure in Endwell, New York, serving as a key player in flood risk reduction along the Patterson Creek. Built in 1966 by the USDA NRCS, this earth dam stands at 65 feet in height and spans 1300 feet in length, with a storage capacity of 1280 acre-feet. The dam's primary purpose is flood risk reduction, with a maximum discharge capability of 17,500 cubic feet per second.
Located in Broome County, this dam is regulated by the NYS DEC and undergoes regular inspections to ensure its operational integrity. With a high hazard potential, the dam is deemed to have a moderate risk level. While its condition assessment remains unrated, the dam has an emergency action plan in place to address any potential risks. The presence of an uncontrolled spillway with a width of 355 feet further highlights the importance of this structure in managing water flow and mitigating the impact of extreme weather events on the surrounding area. For water resource and climate enthusiasts, the Patterson Brixius Grey Watershed 1 Dam serves as a critical piece of infrastructure in safeguarding the community against flooding and ensuring the sustainable management of water resources 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.
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 Patterson Brixius Grey Watershed 1 Dam
Where does the data for Patterson Brixius Grey Watershed 1 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 High 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.
