Summary

This diversion system is designed by the DOI Bureau of Reclamation and serves the primary purpose of irrigation, with additional functions for hydroelectric power generation. Completed in 1959, the Earth-type dam has a height of 67 feet and a structural height of 78 feet, with a storage capacity of 392 acre-feet and a maximum discharge of 2650 cubic feet per second.

The Keene Creek Diversion is situated on Keene Creek and plays a vital role in water resource management and agricultural irrigation in the region. The dam's significant hazard potential underscores the importance of regular inspections and maintenance to ensure its safety and functionality. With a drainage area of 20 square miles and a surface area of 15 acres, this diversion structure is a crucial part of the water infrastructure in Jackson County, Oregon.

As climate change continues to impact water resources and hydrological patterns, the Keene Creek Diversion serves as a critical asset for sustainable water supply and management in the region. With its historical significance and engineering excellence, this diversion system exemplifies the intersection of water resource management, climate resilience, and agricultural sustainability in the Pacific Northwest.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
