Summary
Managed by the Sunnyside Valley Irrigation District (SVID), this offstream reservoir was completed in 2010 and has a storage capacity of 21 acre-feet, with a normal storage level of 15 acre-feet. The reservoir covers a surface area of 4 acres and has a hydraulic height of 9 feet.
This earth dam structure, designed by Doug Lindley and SVID, is regulated by the Washington Department of Ecology and undergoes regular inspections to ensure its safety and functionality. Despite being classified as having a high hazard potential due to its location, the condition assessment reported the structure as satisfactory during the last inspection in June 2017. With its strategic location and critical role in supporting agricultural activities in the region, the SVID Mabton Canal 12.48 Reservoir stands as a key component in water resource management and climate resilience efforts in Yakima County, Washington.
As a public utility infrastructure, the SVID Mabton Canal 12.48 Reservoir plays a crucial role in water management and irrigation for the surrounding agricultural lands. With its completion in 2010, this reservoir provides essential water storage capacity and contributes to the overall water security and sustainability of the region. The ongoing regulatory oversight and maintenance efforts ensure the continued functionality and safety of this earth dam structure, highlighting its importance in supporting the local economy and water resource management practices.

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.
