Dillard Lumber Co Dike dam
Dillard Lumber Co Dike
The Dillard Lumber CO Dike, also known as the Dillard Lumber Log Pond, is a private earth dam located in Douglas County, Oregon. Completed in 1946, this dam spans 3,100 feet in length and has a height of 15 feet, with a maximum storage capacity of 285 acre-feet. Situated along the South Umpqua River, this dam serves a primary purpose of "Other" and is regulated by the Oregon Water Resources Department.
With a significant hazard potential and a condition assessment that is currently not rated, the Dillard Lumber CO Dike is inspected every three years to ensure its structural integrity and safety. The dam features a slide (sluice gate) outlet gate and is designed to handle a maximum discharge of 50 cubic feet per second. Despite being privately owned, the dam falls under state jurisdiction and is subject to permitting, inspection, and enforcement by the relevant regulatory agencies.
For water resource and climate enthusiasts, the Dillard Lumber CO Dike represents a vital infrastructure that plays a crucial role in managing water resources in the region. Its proximity to the South Umpqua River and the significant storage capacity it provides make it an essential component of the local water management system. With its historical significance and ongoing regulatory oversight, this dam serves as a focal point for understanding the intersection of human activity, water resource management, and environmental stewardship in the Pacific Northwest.

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 Dillard Lumber Co Dike
Where does the data for Dillard Lumber Co Dike 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.
