Summary
The dam, with a hydraulic height of 28 feet, holds a storage capacity of 6800 acre-feet and covers a surface area of 350 acres. It is primarily designed as a buttress dam, supported by a multi-arch core type and built on a soil foundation.
Managed by the Washington Department of Ecology, the dam is regulated and inspected regularly to ensure its safety and efficiency. With a high hazard potential due to its location on Lacamas Creek, the dam is assessed to be in satisfactory condition as of April 2018. Emergency action plans are in place, though details of their last revision and effectiveness meeting guidelines are not specified in available data.
The surrounding area offers recreational opportunities, in addition to its water supply function. The dam, situated in a scenic location, plays a vital role in maintaining water levels for both practical and leisure purposes. Climate and water resource enthusiasts will appreciate the significance of Lacamas & Round Lakes Upper Dam as a key infrastructure supporting the region's water needs while contributing to environmental conservation efforts.

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.
