Summary

Designed by Ken Ritz of Tyson Fresh Meats, this Earth-type dam stands at a hydraulic height of 17 feet and a structural height of 13 feet, with a length of 1600 feet and a storage capacity of 38 acre-feet. Completed in 2010, the dam serves a primary purpose other than water storage, with a hazard potential deemed significant but its condition assessed as satisfactory during the last inspection in September 2021.

With a drainage area of only 0.01 square miles, Tyson Fresh Meats Pasco Brine Pond 8 has a surface area of 3.5 acres and a normal storage capacity of 27 acre-feet. The dam's maximum discharge rate is 1 cubic foot per second, and it has yet to undergo significant modifications since its completion. The facility is subject to regular inspections, with the last one conducted in September 2021, indicating a satisfactory condition and a hazard potential that necessitates attention.

As a vital water resource in the region, Tyson Fresh Meats Pasco Brine Pond 8 plays a crucial role in water management and conservation efforts. With its regulated status and significant hazard potential, the dam serves as a key infrastructure for the local community and underscores the importance of sustainable water resource management practices in the face of changing climate conditions.

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.
