Mallories Dairy Lagoon #2 dam
Mallories Dairy Lagoon #2
Mallories Dairy Lagoon #2 is a private water resource located in Marion, Oregon, serving primarily for irrigation purposes. Managed by the Oregon Water Resources Department, this earth dam stands at a height of 21.8 feet and has a storage capacity of 84 acre-feet. While the dam has a low hazard potential, it is regularly inspected every six years to ensure its structural integrity and safe operation.
Situated in a rural area with coordinates 45.01555833 latitude and -122.8269806 longitude, Mallories Dairy Lagoon #2 features a slide gate as its outlet control structure. Despite not having a designated completion year or having undergone modifications, the dam is crucial for supporting local agricultural activities through reliable water supply. The dam's condition is currently not rated, but its low hazard potential suggests minimal risks of failure and potential environmental impacts.
As part of the Portland District, Mallories Dairy Lagoon #2 stands as a vital water management infrastructure in the region, contributing to the sustainability of irrigation practices and water resource utilization. With its regulated state permitting and inspection processes, the dam ensures compliance with safety standards and effective emergency response measures. For water resource and climate enthusiasts, Mallories Dairy Lagoon #2 represents a critical piece of the local water infrastructure, supporting agricultural productivity and environmental stewardship in Marion County, 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 Mallories Dairy Lagoon #2
Where does the data for Mallories Dairy Lagoon #2 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 Low 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.
