Peterson dam
Peterson
Peterson, Floyd is a privately owned dam located in Marion, Oregon, along the Abiqua Creek tributary. Completed in 1977, this earth dam stands at a height of 26.7 meters and serves primarily for recreational purposes, with a storage capacity of 19 acre-feet and a surface area of 2.15 acres. The dam has a significant hazard potential and is regulated by the Oregon Water Resources Department, with regular inspections conducted to ensure its safety and compliance with state regulations.
Despite its remote location in Silverton, Peterson, Floyd plays a crucial role in providing recreational opportunities for the local community. The dam features a slide (sluice gate) outlet gate and a spillway type that is not specified in the data. With a maximum discharge of 265 cubic feet per second, the dam contributes to the management of water resources in the area and supports the ecological health of the Abiqua Creek watershed. Additionally, the dam's structural height of 27 meters and hydraulic height of 23 meters highlight its importance in maintaining water levels and flow in the region.
As an integral part of the water infrastructure in Oregon, Peterson, Floyd represents a blend of human ingenuity and natural resource management. The dam's presence underscores the complex relationship between water resources and climate, as it provides both recreational benefits and potential risks if not properly maintained. With its state-regulated status and regular inspections, Peterson, Floyd stands as a testament to the ongoing efforts to balance the needs of water users while safeguarding the environment for future generations.

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 Peterson
Where does the data for Peterson 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.
