ASTORIA — The Columbia River Maritime Museum will kick off its five-week Past to Present Lecture Series on Jan. 14 with the topic of salmon health and migration.

Graham Klag, executive director of the North Coast Watershed Association, and Kelli Daffron, project manager, will present “Dams and Traffic Jams: Impacts on Water and Salmon” at 11 a.m. in the museum’s Ford Room.

The talk will share how the North Coast Watershed Association is working with partners to mitigate the effects of hatchery dams on salmon migration, including at the Klaskanine Salmon Hatchery in Olney.

Klag and Daffron will also talk about the harmful effects of 6PPD-quinone, a chemical derived from tires, on coho salmon and other aquatic life.

On Jan. 21, the museum will welcome Depoe Bay-based author Rob Scher, for a talk titled “The Tragic Voyage of the USS Valencia: What Doomed the Ship of Lost Souls?”

Rounding out the series are talks on castaway adventures in historical manga by historian Jim Mockford on Jan. 28; a history of the International Longshore and Warehouse Union by longshoremen Jared Moultrie and Josh Goodwin on Feb. 5; and a talk on the U.S. Life-Saving Service in the Pacific Northwest by museum education director Katy Menne.

All lectures begin at 11 a.m. Tuesdays in the Ford Room and are included with museum admission. Lectures are free to attend for museum members. For more details about upcoming programs, visit www.crmm.org.
