Christie Brook Dike dam
Christie Brook Dike
Christie Brook Dike, also known as Lake Wanoksink, is a state-owned earth dam located in Sloatsburg, Rockland County, New York. Built in 1934, this dam serves primarily for recreational purposes and has a height of 25 feet and a length of 120 feet. With a storage capacity of 380 acre-feet, it provides a surface area of 38 acres and has a drainage area of 0.9 square miles. Despite being rated as having a low hazard potential, its risk assessment is considered high.
Managed by the New York State Department of Environmental Conservation, Christie Brook Dike is regulated, permitted, inspected, and enforced by the state agency. Although it has not been rated in terms of condition assessment, the dam has not undergone any modifications in recent years. With no spillway present, this dam relies on the natural flow of Pine Meadow Brook as its outlet. Additionally, the dam does not have an Emergency Action Plan prepared or updated, indicating potential gaps in emergency response measures for the area.
Overall, Christie Brook Dike provides a valuable recreational resource in the region, while also posing a potential risk due to its high-risk assessment rating. As a state-regulated structure, it is important to monitor and address any maintenance or safety concerns to ensure the continued safety and functionality of the dam for both recreational enjoyment and water resource management in the area.

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 Christie Brook Dike
Where does the data for Christie Brook Dike 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.
