Heater Reservoir #2 dam
Heater Reservoir #2
Heater Reservoir #2, also known as Upper Heater Res., is a private-owned reservoir located in Marion, Oregon, along the Center Fork Drift Creek. This reservoir was completed in 1981 and has a primary purpose of irrigation, with a storage capacity of 42.5 acre-feet and a surface area of 4.65 acres. With a significant hazard potential, the dam stands at a height of 28 feet, serving as a crucial water resource for the surrounding area.
Managed by the Oregon Water Resources Department, Heater Reservoir #2 is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and functionality. The dam is of earth type, with a hydraulic height of 24 feet and a length of 290 feet. Despite being classified as not rated in terms of condition assessment, the reservoir plays a vital role in water management for irrigation purposes in the region.
With a maximum discharge of 82 cubic feet per second, Heater Reservoir #2 poses a significant risk if not properly maintained and managed. The dam has no spillway type specified, but with regular inspections and a designated inspection frequency of 3 years, efforts are made to mitigate potential hazards and ensure the safety of the structure. As a key component of the local water infrastructure, this reservoir serves as a critical resource for water supply and irrigation in the area.

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 Heater Reservoir #2
Where does the data for Heater Reservoir #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 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.
