Thompson Valley Diversion (Slid) dam
Thompson Valley Diversion (Slid)
The Thompson Valley Diversion, also known as the S.L.I.D. Diversion Dam, is a private water structure located in Silver Lake, Oregon. Completed in 1915, this Earth-type dam stands at a height of 48 feet and serves the primary purpose of irrigation in the area. With a storage capacity of 460 acre-feet and a maximum discharge of 5000 cubic feet per second, the dam plays a crucial role in managing water resources for the surrounding region.
Owned privately, the Thompson Valley Diversion is regulated by the Oregon Water Resources Department (OWRD) and undergoes regular inspections to ensure its structural integrity and compliance with state regulations. With a significant hazard potential, this dam is classified as "Not Rated" in terms of its condition assessment, highlighting the need for ongoing monitoring and maintenance. The dam's location on the Silver and West Fork Silver Creek rivers underscores its importance in water management for the local community.
As a key feature in the irrigation infrastructure of the region, the Thompson Valley Diversion provides essential water resources for agricultural activities and supports the livelihoods of many individuals in the area. With its historical significance dating back over a century, this dam continues to play a vital role in water resource management and climate adaptation efforts in Silver Lake, Oregon.

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 Thompson Valley Diversion (Slid)
Where does the data for Thompson Valley Diversion (Slid) 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 Significant 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.
