Cuba Lake Outlet Spillway Dam dam
Cuba Lake Outlet Spillway Dam
Located in Maplehurst, Allegany, New York, the Cuba Lake Outlet Spillway Dam is a concrete structure completed in 1919 for recreational purposes. With a height of 9 feet and a length of 136 feet, this dam has a storage capacity of 16,498 acre-feet and covers a surface area of 465 acres. It is regulated by the New York State Department of Environmental Conservation, with inspection, permitting, and enforcement protocols in place.
The spillway type of the Cuba Lake Outlet Dam is controlled, with a width of 102 feet and a maximum discharge capacity of 800 cubic feet per second. Despite being classified as having a significant hazard potential, the dam's condition is currently not rated. Emergency action plans have been prepared, with the last revision in January 2019, ensuring that the risk of inundation is managed effectively. Congressional District 23, represented by Tom Reed, oversees this vital water resource infrastructure in New York.
Overall, the Cuba Lake Outlet Spillway Dam serves as a crucial recreational and water management asset, providing both enjoyment and safety to the surrounding community. With a high risk assessment but proper risk management measures in place, this dam showcases the importance of maintaining and monitoring water resources in the face of changing climate conditions.
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.
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 Cuba Lake Outlet Spillway Dam
Where does the data for Cuba Lake Outlet Spillway 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.
