Van Dyke Dam dam
Van Dyke Dam
Van Dyke Dam, also known as Lake Zambobawa Dam, is a private-owned structure located in Rindge, New Hampshire. Completed in 1982, the dam serves primarily for recreational purposes, with a storage capacity of 66 acre-feet and a normal storage level of 39 acre-feet. Situated on the Monomonac Brook, the dam has a height of 8 feet and a length of 94 feet, with a surface area of 18 acres and a drainage area of 2.76 square miles.
Managed by the NHDES Dam Bureau, the dam is regulated, permitted, inspected, and enforced by the state. It has a low hazard potential and is currently in fair condition, as assessed during the last inspection in September 2016. The spillway type is uncontrolled, with a width of 20 feet, and the maximum discharge capability is 1182 cubic feet per second. While the risk assessment indicates a moderate level of risk, the dam is not owned or funded by any federal agency, operating solely under private ownership.
Overall, Van Dyke Dam stands as a vital structure for recreational activities in the Cheshire County area. With its picturesque location and important water resource functions, the dam provides a serene setting for visitors to enjoy outdoor activities along the beautiful Lake Zambobawa. Though it poses a moderate level of risk, the dam's operational and safety measures ensure the protection of its surrounding community and environment, making it a valuable asset for water resource and climate enthusiasts to appreciate and protect.

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 Van Dyke Dam
Where does the data for Van Dyke 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 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.
