L Hance Wetland Reserve Dam dam
L Hance Wetland Reserve Dam
The L Hance Wetland Reserve Dam, located in Somerville, New York, serves as a vital resource for fish and wildlife, specifically designed as a Fish and Wildlife Pond. Completed in 2000, this Earth-type dam stands at a height of 10 feet and has a storage capacity of 59 acre-feet. The dam is regulated by the NYS DEC and is inspected regularly to ensure its structural integrity and safety.
With a low hazard potential and a moderate risk assessment rating, the L Hance Wetland Reserve Dam plays a crucial role in managing water resources in the area. Situated along the Malterna Creek, the dam helps control water flow, with a maximum discharge capacity of 443 cubic feet per second. The surrounding wetlands benefit from the dam's presence, providing a habitat for various species and contributing to the overall health of the ecosystem.
Enthusiasts interested in water resource management and climate resilience will find the L Hance Wetland Reserve Dam to be a fascinating example of how infrastructure can support both wildlife conservation and flood control efforts. As a privately owned structure, the dam demonstrates the importance of collaboration between private landowners and regulatory agencies in ensuring the sustainability of water resources for future generations.

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 L Hance Wetland Reserve Dam
Where does the data for L Hance Wetland Reserve 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.
