Drain Plywood Log Pond dam
Drain Plywood Log Pond
The Drain Plywood Log Pond, located in Elkton, Oregon, is a privately owned earth dam that was completed in 1956. With a dam height of 13 feet and a maximum storage capacity of 176 acre-feet, this structure serves a primary purpose that is classified as 'Other'. The dam is situated on Elk Creek and is under state regulation, with permitting, inspection, and enforcement handled by the Oregon Water Resources Department.
Despite being rated as having a 'Significant' hazard potential, the condition of the Drain Plywood Log Pond dam is currently listed as 'Not Rated'. The structure features a slide (sluice gate) outlet gate and has undergone an inspection frequency of 3 times, with the last inspection taking place on January 13, 2021. While the dam is not operated by a federal agency, it falls within the jurisdiction of the Portland District of the US Army Corps of Engineers.
Water resource and climate enthusiasts interested in the management and maintenance of dams in the Elkton area will find the Drain Plywood Log Pond to be an intriguing case study. With its unique design characteristics and state-regulated status, this earth dam serves as a vital component in the local water infrastructure, highlighting the intersection of human engineering with natural resource conservation in a dynamic ecosystem like Elk Creek.

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 Drain Plywood Log Pond
Where does the data for Drain Plywood Log Pond 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.
