Spring Lake Dam dam
Spring Lake Dam
Spring Lake Dam, also known as Croaker Lake, is a masonry dam located in East White Plains, New York. Completed in 1895, the dam serves primarily for recreational purposes, with a height of 20 feet and a length of 250 feet. It is situated on the TR-Mamaroneck River and has a storage capacity of 20 acre-feet, providing a surface area of 3 acres for recreational activities.
Despite its historical significance, Spring Lake Dam is facing significant challenges in terms of its condition and hazard potential. A recent assessment categorized its condition as poor, with a significant hazard potential. The last inspection in June 2019 revealed the need for maintenance and improvements to ensure the safety and functionality of the dam. The risk assessment also indicates a moderate risk level, prompting the need for proactive risk management measures.
With its picturesque setting and recreational value, Spring Lake Dam presents an opportunity for stakeholders and regulators to collaborate on enhancing its safety and longevity. The dam is under state jurisdiction and regulation, with the NYS DEC overseeing permitting, inspection, and enforcement. By addressing the dam's current condition and hazard potential, stakeholders can ensure the continued enjoyment of Spring Lake for water resource and climate enthusiasts while safeguarding against potential risks associated with aging infrastructure.
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 Spring Lake Dam
Where does the data for Spring Lake 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.
