The Umpqua pikeminnow formerly called the Umpqua squawfish (Ptychocheilus umpquae) is a species of freshwater ray-finned fish belonging to the family Leuciscidae, the daces, chubs, Eurasian minnows and related species. This large fish is endemic to Oregon, and is the smallest species of pikeminnow. It is native to the Umpqua and Siuslaw river drainages.

Description
The Umpqua pikeminnow has around 60 to 63 scales between the head and dorsal fin. It also usually has 66 to 81 scales along its lateral line, 9 rays on its dorsal fin, and 8 rays on its anal fin. They can reach 44 cm (17 in) in total length, but are more often 31 cm (12 in).
Range & habitat
Umpqua pikeminnow are found in the Southwest part of Oregon, usually along the Umpqua and Siuslaw river drainages, as well as the Siltcoos, Woahink, and Tahkenitch lakes. It has also been introduced in the Rogue River. The Rogue River introduction has two possible sources: 1) in 1994 a flood breached the north Rogue drainage divide, causing pikeminnow to escape through the Cow Creek system, or 2) in 1978 through an unscreened farm pond on Wolf Creek. The fish inhabit the pools or sluggish runs of small rivers and creeks, usually found in waters less than 1 m deep.
