Summary

This Earth-type dam, completed in 1980, stands at a height of 7 feet and has a storage capacity of 69 acre-feet. With a surface area of 9.3 acres and a drainage area of 0.01 square miles, this lagoon system serves a primary purpose classified as "Other."

Despite its satisfactory condition assessment as of October 2018, Tyson Fresh Meats Lagoons 1 2 3 poses a significant hazard potential, emphasizing the importance of regular inspections and maintenance. The dam's emergency action plan was last revised in March 2020, and the facility has an inspection frequency of every 5 years. The surrounding area, including Congressional District 04 represented by Dan Newhouse, may benefit from increased awareness of the lagoon's risk management measures and potential inundation maps to ensure preparedness in case of emergency.

Water resource and climate enthusiasts in the region should take note of Tyson Fresh Meats Lagoons 1 2 3 as a significant Earth dam structure with a vital role in water storage and management. Understanding its operational and regulatory aspects, including state jurisdiction, permitting, and enforcement, is crucial for promoting sustainable water resource practices and ensuring the safety of the surrounding community and environment.

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.
