Summary

The farm operates an earth dam completed in 1994 for irrigation purposes, with a storage capacity of 675 acre-feet and a surface area of 72.3 acres. The dam has a structural height of 20 feet and a hazard potential rated as significant.

Managed by the Oregon Water Resources Department, Katz Farm's dam plays a crucial role in maintaining water levels for fish and wildlife ponds, as well as supporting irrigation activities. The farm is subject to state regulation, permitting, inspection, and enforcement to ensure the safety and sustainability of its water management practices. Located off-channel from a river or stream, the farm's dam contributes to the overall water resource management in the area.

With its proximity to the Portland District of the US Army Corps of Engineers, Katz Farm is a key player in the local water infrastructure landscape. The farm's dam, while not rated for condition assessment, underscores the importance of private landowners in supporting water conservation efforts and mitigating potential risks associated with dam operations. As a vital link in the chain of water resource management, Katz Farm showcases the intersection of agriculture, water conservation, and environmental stewardship in the region.

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.
