Description
- Abstract: Rickreall Creek is a 4th order tributary of the Willamette River in Polk County, Oregon (Mattson and Gallagher 2001). Previous fish sampling had indicated a high percentage of exotic fishes in the lower portion of the creek (Altman 1997) and in an upstream reservoir (Chastain et. al. 2002). However, within the mainstem, exotic fishes (with the exception of planted juvenile coho) are absent above Villwok's Ford, the lowermost barrier on the creek at about river km 12.7 (Chastain et. al. 2002). A 1995 CH2MHill survey noted the ford was a culvert and not passable while Mattson and Gallagher (2001) found water flowing over the ford and fish passage "appeared possible". Because the ford appears to violate Oregon statutes regarding fish passage at man-made barriers, but may paradoxically provide benefits by excluding exotic fishes, we initiated a study of the ford and of a variety of fishes to determine the seasons and conditions during which the ford was a barrier to fish passage.
