Nancy Lawson Dam dam
Nancy Lawson Dam
Nancy Lawson Dam, located in Clarksville, New York, was completed in 1996 and serves as a vital recreational resource for the community. This private earth dam stands at a height of 20 feet, with a length of 168 feet, and has a storage capacity of 107.5 acre-feet. The dam's primary purpose is for recreation, offering a surface area of 7.6 acres for outdoor activities such as fishing, boating, and picnicking.
Managed by the New York State Department of Environmental Conservation (NYS DEC), Nancy Lawson Dam is regulated, permitted, inspected, and enforced by the state to ensure its safety and functionality. Despite being rated as having a low hazard potential and not yet assessed for conditions, the dam is classified as having a moderate risk level (3). The spillway type is uncontrolled, with a width of 44 feet, providing necessary water release during high flow events.
For water resource and climate enthusiasts interested in conservation efforts and sustainable management of dams, Nancy Lawson Dam stands as a testament to responsible stewardship and the importance of recreational water infrastructure in enhancing community well-being and environmental resilience. The dam's presence along the TR-T6-ONESQUETHAW river/stream underscores the interconnectedness of water resources and outdoor recreation, highlighting the significance of safeguarding such structures for future generations to enjoy.

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 Nancy Lawson Dam
Where does the data for Nancy Lawson 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.
