Little Choconut Site 1a Dam dam
Little Choconut Site 1a Dam
Little Choconut Site 1a Dam, also known as Finch Hollow Site 1a Dam, is a local government-owned structure located in Johnson City, New York. This earth dam, completed in 1969 by the USDA NRCS, serves primarily for flood risk reduction along the TR-Susquehanna River. With a height of 35 feet and a length of 525 feet, the dam has a storage capacity of 340 acre-feet and a maximum discharge of 7730 cubic feet per second.
Managed by the NYS DEC, this dam is state-regulated and regularly inspected to ensure its safety and effectiveness. Although its hazard potential is rated as high, the condition assessment is currently not rated. The emergency action plan for the dam was last revised in January 2020, indicating a commitment to preparedness and risk management. Overall, the Little Choconut Site 1a Dam plays a crucial role in protecting the surrounding area from flooding events, with a moderate risk level assigned to its operation and maintenance.
Enthusiasts of water resources and climate will find the details of this dam's specifications and regulatory oversight fascinating. Its association with flood risk reduction and its location on the Susquehanna River make it a key infrastructure for water management in the region. Despite its high hazard potential, the dam's regular inspections and emergency preparedness measures highlight a commitment to ensuring public safety and minimizing potential risks associated with its operation.

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 Little Choconut Site 1a Dam
Where does the data for Little Choconut Site 1a 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 High 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.
