Solmar Lake Dam, located in Clallam, Washington, is a privately owned structure regulated by the Washington Dept of Ecology for its recreational purposes. Completed in 1968, this earth dam stands at a hydraulic height of 16 feet and stretches 400 feet in length, holding a storage capacity of 38 acre-feet for the Tr-McDonald Creek. Its high hazard potential is mitigated by a satisfactory condition assessment as of September 2015, with inspections conducted every five years.

The dam's design, with a stone core and soil foundation, provides a structural height of 16 feet to maintain normal storage levels of 34 acre-feet over a 7-acre surface area. While no spillway information is available, the dam's maximum discharge capacity is recorded at 6 cubic feet per second. Despite its potential risks, Solmar Lake Dam has yet to undergo modifications since its completion, reflecting a stable operational history that aligns with its primary purpose of recreation for the local community and visitors.

In the congressional district represented by Derek Kilmer, Solmar Lake Dam remains a key feature for water resource and climate enthusiasts, serving as both a recreational hub and a regulated infrastructure for environmental stewardship. With continued state inspection and enforcement, this dam stands as a testament to responsible ownership and management in ensuring the safety and sustainability of water resources in the region.
