Summary
Completed in 1976, this rockfill dam serves primarily for recreation purposes along the Tr-Lower Crab Creek. With a hydraulic height of 10 feet and a structural height of 7 feet, Lenice Dam has a normal storage capacity of 110 acre-feet, contributing to a surface area of 94 acres and a drainage area of 20.7 square miles.
The dam's low hazard potential and current condition assessment of "Not Rated" indicate a stable and well-maintained structure. While the last inspection took place in 1998, the dam's emergency action plan status and risk assessment details remain unspecified. Lenice Dam stands as a significant landmark in Grant County, Washington, offering a recreational haven for water resource and climate enthusiasts to explore and enjoy the surrounding natural beauty.
Situated in Congressional District 04, Lenice Dam represents a vital asset in the region's water management infrastructure. With its historical significance and contribution to local recreation opportunities, the dam stands as a testament to Washington's commitment to safeguarding its water resources for both practical and leisure purposes. As a state-regulated and inspected structure, Lenice Dam continues to play a crucial role in supporting the ecological balance and recreational activities in the area.

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.
