Summary
The dam stands at 68 feet high with a hydraulic height of 56 feet and a length of 620 feet, providing a storage capacity of 102,000 acre-feet. Its spillway type is uncontrolled with a width of 40 feet, and it has an outlet gate in the form of a slide (sluice gate).
Despite being classified as having a high hazard potential, Woodruff Narrows is currently in fair condition, as assessed during the last inspection in July 2018. The dam's risk assessment is moderate, with measures in place to manage any potential risks associated with its operation. The surrounding area covers 2312 acres, with a drainage area of 870 acres and a maximum discharge capacity of 11,000 cubic feet per second, making it a vital component in the local water resource management system.
Woodruff Narrows plays a crucial role in the irrigation infrastructure of the region, serving as a key storage facility for water from the Bear River. With its strategic location and substantial storage capacity, this earth dam continues to support agricultural activities and water resource management efforts in the area, contributing to the sustainable use of water in Wyoming.

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.
