In 2012, scholars reported new dates on the Zamostje 2 weirs near Moscow, Russia, of more than 7,500 years ago.

How old are fish weirs in British Columbia?

Glenrose Cannery at the mouth of the Fraser River in British Columbia dates to about 4000–4500 RCYBP (4500-5280 cal BP). Fish weirs in southeastern Alaska date to ca. 3,000 years ago. Some government-sponsored programs have been funded to blend traditional fish weir knowledge from indigenous peoples with scientific research.
