Morningside Lake Dam dam
Morningside Lake Dam
Morningside Lake Dam, located in South Fallsburg, New York, is a concrete structure completed in 1945 for recreational purposes. The dam stands at a height of 10 feet and spans a length of 220 feet, with a storage capacity of 475 acre-feet. It is situated on the Sheldrake Stream and is regulated by the New York State Department of Environmental Conservation.
Despite being rated as having a low hazard potential, the dam poses a very high risk due to its condition assessment being listed as "Not Rated." The last inspection was conducted in June 2011, and no emergency action plan or inundation maps have been prepared. The dam is under state jurisdiction and is subject to regular inspections, permitting, and enforcement.
For water resource and climate enthusiasts, Morningside Lake Dam serves as an intriguing case study in dam management and risk assessment. With its recreational purpose and historical significance, the dam presents a unique opportunity to explore the intersection of water infrastructure, environmental regulations, and emergency preparedness in the face of potential hazards. Researchers and policymakers alike may find value in further examining the risk management measures and potential updates needed for this dam to ensure the safety and sustainability of Morningside Lake and its surrounding community.

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 Morningside Lake Dam
Where does the data for Morningside Lake 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.
