North Fork Diversion Dam dam
North Fork Diversion Dam
The North Fork Diversion Dam, also known as the Prospect Project, is a concrete dam located on the North Fork Rogue River in Jackson County, Oregon. Built in 1965, this dam serves a primary purpose of hydroelectric power generation and has a height of 50 feet. With a storage capacity of 309 acre-feet, the dam contributes significantly to the water resource management in the region by regulating the flow of the river and providing a sustainable source of energy.
Owned by a public utility and regulated by the Oregon Water Resources Department, the North Fork Diversion Dam plays a crucial role in the state's water infrastructure. Despite its significant hazard potential, the dam's condition assessment is currently not rated. However, with a maximum discharge capacity of 275 cubic feet per second and a drainage area of 508 square miles, the dam is well-equipped to handle potential risks and emergencies, although more detailed risk management measures may need to be developed in the future.
Overall, the North Fork Diversion Dam is a vital structure in Oregon's water resource network, providing both hydroelectric power and water management capabilities. Its location on the North Fork Rogue River and its impressive storage capacity make it a key player in the region's climate resilience and energy sustainability efforts. As the dam continues to be monitored and regulated by state authorities, it remains an essential component of the local water supply and environmental management system.

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 North Fork Diversion Dam
Where does the data for North Fork Diversion Dam 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.
