Summary

Managed by the GALLI GROUP, this reservoir serves primarily for irrigation purposes and is regulated by the Oregon Water Resources Department. Situated in a picturesque location at coordinates 42.57717895 latitude and -123.1887894 longitude, it is part of the UNNAMED tributary of Pleasant Creek.

With a dam height of 26 feet and a storage capacity of 90 acre-feet, Ditch Creek Reservoir boasts a low hazard potential and has undergone inspections every 6 years as of its last assessment in March 2015. The reservoir features a Needle outlet gate and is considered to have not been rated in terms of its condition assessment. While no major modifications or enhancements have been recorded, the reservoir continues to play a vital role in supporting irrigation needs in the region.

Enthusiasts of water resources and climate will find Ditch Creek Reservoir an intriguing case study of a privately owned water source in Oregon. Its peaceful surroundings, essential role in irrigation, and regulatory oversight by the state make it a compelling subject for further exploration and study in the realm of water management and sustainability.

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.
