## 30-Second Historical Snapshot

Before European settlement, Willamette Falls was known as *Tumwata* ('waterfall'), serving as the primary salmon and Pacific lamprey dipnet fishery and economic trading capital for the Clackamas and Clowwewalla tribes, who harvested fish along the basalt shelves for over 10,000 years. 

## 1\. The Cascades of Wealth: Dipnetting Spring Chinook & Lamprey

**The basalt horseshoe of Tumwata served as a natural barrier where millions of migrating fish were concentrated in boiling pools at the base of the 40-foot falls.** Standing precariously on wet wooden scaffolds lashed directly to basalt rock faces, indigenous fishermen used long-handled dipnets woven from wild nettle and cedar bark to scoop Spring Chinook salmon from the spray.

Equally vital to tribal survival was the annual harvest of Pacific lamprey (*skakwal*). These ancient, eel-like fish used their suction mouths to climb the wet vertical basalt cliffs. Native families gathered along the basalt crevices at night, harvesting lamprey by hand or with specialized wooden hooks for smoking, oil extraction, and winter nourishment.

## 2\. The Clowwewalla Trading Empire

**Tumwata was not merely a seasonal food source; it was the Wall Street of pre-contact Oregon.** Positioned at the vital interface between the navigable lower Willamette and the upper agricultural valleys, the resident Clowwewalla (Willamette Band) controlled access to the portage around the falls, extracting trade tolls from visiting tribes.

During peak summer runs, thousands of traders from the Klickitat, Molalla, Kalapuya, and coastal Chinookan tribes congregated on the gravel bars below the falls. Dried smoked salmon, prized dentalium shell currency, obsidian from central Oregon, and dried camas bulbs gathered from the nearby upland meadows of West Linn were exchanged in a bustling inter-tribal marketplace.

## 3\. Disruption, Resilience & Modern Stewardship

**The arrival of maritime and overland fur traders in the early 19th century brought catastrophic viral epidemics that decimated indigenous river villages.** Between 1829 and 1833, waves of introduced malaria and measles wiped out an estimated 80 to 90 percent of the lower Willamette native population.

Under the Willamette Valley Treaty of 1855, surviving Clackamas and Clowwewalla people were forcibly relocated to the Grand Ronde Reservation. Today, the Confederated Tribes of the Grand Ronde maintain sovereign fishing rights at Willamette Falls, operating modern ceremonial dipnet platforms and spearheading the ecological restoration of the historic waterfall corridor.

### Frequently Asked Questions

#### What does the word "Tumwata" mean?

In Chinook Jargon (the historic trade language of the Pacific Northwest), Tumwata literally means 'waterfall' or 'noisy, thundering water'.

#### Do Native American tribes still fish at Willamette Falls today?

Yes. Under protected federal treaty agreements, members of the Confederated Tribes of the Grand Ronde continue to harvest Pacific lamprey and Spring Chinook using traditional platforms at the base of the falls.
