About this dam

Lower Chia Lin Dam

Lower Chia Lin Dam, also known as Camp Alamar Lower Lake Dam, is a captivating water resource located in Allen Corners, Dutchess County, New York. Constructed in 1950, this earth dam serves primarily for recreational purposes, offering a serene 5.7-acre surface area for visitors to enjoy. With a height of 18 feet and a storage capacity of 76.2 acre-feet, the dam is regulated by the New York State Department of Environmental Conservation and undergoes regular inspections to ensure its safety and functionality.

The dam's spillway, measuring 20 feet in width, is uncontrolled, allowing for a maximum discharge of 120 cubic feet per second. Despite its fair condition assessment and significant hazard potential, the dam is considered a moderate risk (3) and is equipped with emergency action plans to mitigate any potential risks in case of emergencies. With its picturesque location alongside Leetown Brook, Lower Chia Lin Dam offers a tranquil setting for water and climate enthusiasts to appreciate and explore, showcasing the harmonious relationship between water resources and recreational opportunities in the region.

As a vital part of the local government's infrastructure, Lower Chia Lin Dam stands as a testament to the importance of responsible water resource management. Its presence not only provides a recreational haven for the community but also serves as a reminder of the delicate balance between human activities and the natural environment. With its regulated operations and commitment to safety, this dam exemplifies the efforts to ensure sustainable water resource practices while offering a serene retreat for visitors to immerse themselves in the beauty of the surrounding landscape.

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.

FAQ

About Lower Chia Lin Dam

Where does the data for Lower Chia Lin 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.
