Iman Lake Dam dam
Iman Lake Dam
Iman Lake Dam, also known as Wy'East Lake Dam, is a private-owned structure located in Skamania, Washington. Completed in 1996, this earth dam serves primarily for irrigation purposes, with a hydraulic height of 16.4 feet and a structural height of 14.4 feet. The dam has a storage capacity of 32 acre-feet and covers a surface area of 4.22 acres, with a drainage area of 0.53 square miles.
Managed by the Washington Department of Ecology, Iman Lake Dam poses a high hazard potential but is currently in fair condition as of the last inspection in August 2020. With a state-regulated status, this dam undergoes regular inspections and enforcement measures to ensure its safety and functionality. Despite its age, the dam continues to serve its purpose effectively, providing valuable water resources for irrigation in the region.
Situated on Foster Creek in Congressional District 03, Washington, Iman Lake Dam plays a crucial role in water management and climate resilience in the area. Its strategic location and design make it a key infrastructure for maintaining water supply and supporting agricultural activities. As water resource and climate enthusiasts, it is important to monitor and support the upkeep of such vital structures to ensure sustainable water management for future generations.

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 Iman Lake Dam
Where does the data for Iman 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 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.
