Zielinski Farm Reservoir Dam
Zielinski Farm Reservoir
Zielinski Farm Reservoir, located in Canby, Oregon, is a privately-owned earth dam built in 1974 primarily for irrigation purposes. The reservoir has a storage capacity of 41 acre-feet and covers a surface area of 4.58 acres, serving as a vital water resource for agricultural activities in the region. With a significant hazard potential and a hydraulic height of 22 feet, the dam plays a crucial role in managing water flow in the tributary to Cedar Creek.
Managed by the Oregon Water Resources Department, Zielinski Farm Reservoir undergoes regular state inspections, enforcement, and permitting to ensure its safety and compliance with regulations. The reservoir features a needle outlet gate and has a design height of 26 feet, with a dam length of 300 feet. Although the condition assessment is currently not rated, the reservoir's last inspection was conducted in September 2020, with a scheduled inspection frequency of every 3 years to monitor its structural integrity and operational efficiency.
For water resource and climate enthusiasts, Zielinski Farm Reservoir presents an intriguing example of human intervention in managing water resources for agricultural needs. The reservoir's location in Clackamas County, Oregon, highlights the importance of sustainable water management practices in ensuring a reliable water supply for irrigation purposes. As a significant component of the local water infrastructure, the reservoir showcases the intersection of technology, environmental stewardship, and regulatory oversight in safeguarding water resources for future generations.

About Zielinski Farm Reservoir
Where does the data for Zielinski Farm Reservoir 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 below 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.

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.
