Summary
Managed by SCM Consultants, this reservoir has a maximum storage capacity of 50 acre-feet and a normal storage capacity of 40 acre-feet, covering a surface area of 3.1 acres. The dam's hydraulic height reaches 17 feet, providing regulation of the offstream Esquatzel Coulee.
Regulated by the Washington Department of Ecology, Section 34 Re Reservoir is considered to have a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. Although the dam does not have a spillway type specified, it has a maximum discharge capacity of 30 cubic feet per second. Despite not having an Emergency Action Plan (EAP) prepared or updated, the reservoir meets state regulatory standards for inspection, enforcement, and permitting, ensuring its operational safety and compliance with state jurisdiction.
Overall, Section 34 Re Regulating Reservoir serves as a vital water resource infrastructure in Franklin County, Washington, contributing significantly to local irrigation needs. With its strategic location in the Esquatzel Coulee watershed, this reservoir plays a crucial role in supporting agricultural activities in the region while adhering to state regulations and oversight to maintain its integrity and functionality for the long term.

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.
