Richards Landing Dike I & Ii dam
Richards Landing Dike I & Ii
Richards Landing Dike I & II, also known as Richards Wildlife Dike, is a crucial water resource infrastructure located in St. Lawrence, New York. Built in 1958, this earth dam serves the primary purpose of hydroelectric power generation and navigation on the St. Lawrence River. The dam stands at a height of 45 feet and spans a length of 12,100 feet, with a storage capacity of 803,000 acre-feet.
Managed by the Federal Energy Regulatory Commission, Richards Landing Dike I & II has a high hazard potential and a risk assessment rating of 2, indicating the importance of regular inspections and maintenance. Despite its critical role in the region's water resource management, the condition assessment of the dam is not currently available, highlighting the need for ongoing monitoring and risk management measures. The dam is associated with five other structures and is subject to periodic inspections by the regulatory authorities.
With its strategic location and significant impact on water resource management in the area, Richards Landing Dike I & II is a vital asset that requires careful oversight and maintenance to ensure its continued effectiveness in providing hydroelectric power while safeguarding against potential risks and hazards. Water resource and climate enthusiasts can appreciate the complex infrastructure and regulatory framework that governs this essential piece of the region's water management system.

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 Richards Landing Dike I & Ii
Where does the data for Richards Landing Dike I & Ii 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.
