Yale Saddle Dam dam
Yale Saddle Dam
Yale Saddle Dam, located in Woodland, Washington, is a privately owned structure with a primary purpose of hydroelectric power generation. Completed in 1953, this earth dam stands at a height of 40 feet and has a structural height of 40 feet, with a length of 1600 feet. It has a storage capacity of 402,000 acre-feet and covers a surface area of 3,783 acres, serving as a vital resource for water management in the region.
The dam, situated on the Lewis River, plays a crucial role in supporting various purposes such as fish and wildlife preservation, hydroelectric power generation, and recreational activities. Despite its high hazard potential, with a risk assessment rating of 2, the dam is regulated and inspected by the Federal Energy Regulatory Commission to ensure its safety and structural integrity. With no state jurisdiction or permitting required, the dam remains under federal oversight for its operations and maintenance.
Yale Saddle Dam not only contributes to the local water resource management but also provides a scenic backdrop for recreational activities and wildlife preservation. As a key component of the region's infrastructure, this dam showcases the intersection of human engineering with natural ecosystems, highlighting the importance of sustainable water resource management in the face of changing climate patterns.

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 Yale Saddle Dam
Where does the data for Yale Saddle 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.
