Reoccurrence of the Umpqua Chub (Oregonichthys kalawatseti) in the North Umpqua after almost a century

Abstract

We document the 1st record in 93 y of Umpqua Chub (Oregonichthys kalawatseti) in the North Umpqua River. Although the North Umpqua River has been surveyed for Umpqua Chub over the past 3 decades without success, we captured 34 Umpqua Chub on 14 May 2019, using baited minnow traps, 5.8 km downstream from Winchester Dam on the North Umpqua River. We vouchered 1 specimen for confirmation of field identification at the Oregon State University Ichthyology Collection (OSUIC). Our unexpected capture of Umpqua Chub in the North Umpqua River supports an almost century-old record of the species presence in the river and marks a significant extension of its known range in the Umpqua River basin.
