Summary
Built in 1993 by Tyson Fresh Meats Inc., this Earth-type dam stands at 45 feet with a hydraulic height of 52 feet, providing a maximum storage capacity of 870 acre-feet. The dam serves a crucial purpose in managing water resources for the surrounding area, with a normal storage level of 755 acre-feet and a surface area of 755 acres.
This high-hazard dam on the Tri-Columbia River is regulated by the Washington Dept of Ecology and undergoes regular inspections to ensure its structural integrity. Despite its satisfactory condition assessment as of October 2018, the dam has a hazard potential that necessitates a five-year inspection frequency and an Emergency Action Plan (EAP) preparedness in case of unforeseen events. With a risk assessment and management measures yet to be determined, the Tyson Fresh Meats Storage Pond 4 remains a key infrastructure for water resource management in the region, overseen by state regulatory agencies and local authorities.
As a vital component of the water management system in Walla Walla, Washington, Tyson Fresh Meats Storage Pond 4 plays a crucial role in maintaining water supply and flood control for the area. With its significant storage capacity and strategic location on the Tri-Columbia River, this dam is a testament to the importance of infrastructure in addressing climate change and water resource challenges. As efforts continue to ensure the dam's safety and effectiveness, it remains a focal point for water and climate enthusiasts seeking to understand the intersection of infrastructure, regulation, and environmental stewardship in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
